Because the flow and heat transfer mechanism in the porous medium is not perfect, the research in the direction is continuous, and particularly in the field of reactor thermal engineering and hydraulic power, the research in the direction of flow heat exchange of a spherical fuel pile, accumulation cooling of a melt fragment bed under serious accidents and the like needs to explore the flow heat transfer characteristics in the porous medium containing the internal heat source.

Examples
The embodiment of the invention optimizes the heat release uniformity of the heat source in the porous particle bed based on the background of poor uniformity when the heat source in the particle bed with different specifications is simulated by adopting the inserted electric heating rod. The inventor optimizes the arrangement method of the electric heating rods in the particle bed aiming at the background that the uniformity is poor when the internal heating source in the irregular particle bed is simulated by adopting the inserted electric heating rods, so that the internal heating source simulation mode can continue the phenomenon and mechanism of heat transfer from the broken particles to the pore fluid in the particle bed. In particular to an internal heat source simulation means for the chip bed coolability research experiment of self-heating of chip particles.
In order to solve the technical problem of nonuniform volume heat release in a local unit in the heat source simulation in a particle bed in the prior art, the embodiment of the invention provides a heat release structure, a heat release unit, an internal heat source simulation device and a method. In a first aspect, referring to fig. 1, an embodiment of the present invention provides a heat release structure, including: a first heating rod 10 provided on a first side of a first face of the virtual square; a second heating rod 11 provided on a second side of the second surface of the virtual square; and a third heating rod 12 provided on a third side of the third face of the virtual square; the third surface is arranged between the first surface and the second surface and is perpendicular to the first surface and the second surface respectively; two ends of the third side are respectively vertical to the second side and the third side; the first edge, the second edge and the third edge are not coplanar with each other; the first heating rod, the second heating rod and the third heating rod are all used for being inserted into the particle bed to serve as an internal heat source.
Optionally, the heating rod is an electric heating rod.
Further, the particle bed is an irregular particle bed.
Further, the lengths of the first heating rod, the second heating rod and the third heating rod are the same as the side length of the virtual cube.
Further, the linear power densities of the first heating rod, the second heating rod and the third heating rod are the same.
After the electric heating rods are inserted into the particle bed, the heating source is concentrated to the electric heating rods beside each broken particle, and in order to ensure that the flowing heat transfer process of fluid in the pores of the particle bed is consistent with that of a prototype, the volume heat release power density provided by the electric heating rods is as uniform as possible.
Further, the first, second and third heating rods are spaced apart by a distance less than or equal to 10 times the average particle size of the particles of the particle bed.
The arrangement interval of the electric heating rods directly determines the uniformity degree of the volume heat release of the particle bed, and the smaller and the more uniform the interval is on the premise of not obviously changing the pore structure of the particle bed; in the embodiment of the invention, the arrangement interval is required to be not less than 10 times of the average particle diameter of the particle bed, so that the void structure of the particle bed is not obviously changed by the inserted electric heating rod. Particle beds of different internal heat source powers should be simulated using different thicknesses and different arrangements of spaced electrical heating rods.
Further, the cross-sectional widths of the first heating rod, the second heating rod, and the third heating rod are smaller than the average particle diameter of the particles of the particle bed.
The heat of the single electric heating rod is uniform along the axial direction of the electric heating rod and is non-uniform along the radial direction, and the heat is gradually decreased towards the radial direction far away from the electric heating rod. The thickness of the electric heating rod can also influence the pore structure of the particle bed, the pore structure and the porosity of the particle bed can be obviously changed when the diameter is larger, but the higher the surface power load of the electric heating rod with smaller diameter is, the more difficult the manufacturing is. Optionally, the diameter of the electrically heated rod is no greater than the average particle size of the particle bed.
In a second aspect, embodiments of the present invention provide a heat release unit, as shown with reference to FIGS. 2-4, comprising: a heat release unit constituted by the heat release structure;
Referring to fig. 2, the heat release unit includes:
four edge heating bars 7 which are respectively arranged on two left and right opposite edges of the upper and lower opposite surfaces of the virtual cube;
the central heating rod 5 is arranged on the central line of the virtual cube; and
The two surface heating rods, namely the first surface heating rod 4 and the second surface heating rod 6, are respectively arranged on the front and rear opposite surfaces of the virtual cube, and are respectively parallel to the upper and lower opposite surfaces after passing through the center of each of the front and rear opposite surfaces.
As shown with reference to fig. 3, or a heat release unit includes:
Six heating rods, namely six over-center heating rods 8, are respectively arranged on each surface of the virtual cube, and the heating rods on each surface are parallel to one pair of opposite sides of each surface after passing through the center of each surface; the two heating rods on any opposite surface are parallel to each other, and the two heating rods on any adjacent surface are perpendicular to each other.
Referring to fig. 4, the heat release structure of fig. 1 is included in both fig. 2 and 3. The volume heat release power of fig. 2 and fig. 3 are the same, and are the heating power of three L-length electric heating rods, and after they are subdivided, they are all found to be formed by stacking 8 volume heat release units with L/2 side length, and the L/2 side length of the volume heat release units is the smallest volume heat release unit (which cannot be subdivided, the heat release in the smallest unit is not uniform), that is, the smallest unit where the particle bed volume heat release of the inserted electric heating rod is absolutely uniform. Such a bed of particles packed up with the smallest volume heat release unit exhibits high uniformity, and the volume heat release is not uniform only within the smallest volume heat release unit. The size of the smallest volume heat release unit determines the uniformity of the volumetric heat release of the particulate bed, with smaller sizes being more uniform.
In addition, the heat release characteristics of the heat release structure in three dimensions of X, Y, Z are identical, namely isotropy; the particle beds packed by these minimum volume heat release units must also be isotropic in terms of heat release, which arrangement well eliminates the anisotropic nature of the heat release from the electrical heater rods.
In a third aspect, an embodiment of the present invention provides a device for simulating a heat source in a porous medium with high uniformity, including: and the internal heat source is used for being inserted into the particle bed to serve as an internal heat source and comprises a plurality of heat release structures or heat release units.
In a fourth aspect, an embodiment of the present invention provides a method for simulating a heat source in a porous medium with high uniformity, including:
A number of heating rods are inserted into the particle bed so that a number of said heat release structures 9 are evenly arranged within the particle bed.
Further, the method further comprises:
The linear power density, the thickness and the spacing distance between the heating rods are determined according to the average particle diameter of the particles of the particle bed.
Referring to FIGS. 5-6, schematic diagrams of the arrangement of the electrical heating rods within the cylindrical particulate bed, and detailed description of the simulation method, with reference to the components in the description of the drawings, are shown.
When an internal electric heating rod type internal heat source is designed and inserted in a particle bed (average particle size is 6 mm) with the cylinder inner diameter F of 0.3m, the cylinder height H of 0.7m and the volume heat release power density of 2.0MW/m 3, an electric heating rod 1 arranged in the X direction, an electric heating rod 2 arranged in the Y direction and an electric heating rod 3 arranged in the Z direction are adopted, namely, electric heating rods with the diameter of 4mm are arranged at the intersection interval of X, Y, Z three dimensions to form a heat release structure, when the interval L of the arrangement of the electric heating rods in the same direction in the heat release structure is 6cm, the smallest volume element is a cube with the side length of 3cm, and higher uniformity is shown in a cylinder with the F of 0.3m and the H of 0.7 m.
Non-uniform boundaries inevitably occur near the wall where the first 13 and second 14 and third 15 heat release grids are substantially equal and the fourth 16 heat release grids are 15% higher than the central volume heat release, but these grids are corner regions 30mm apart, the effect of which is negligible compared to uniform volume heat release in the Φ0.3m region.
The linear power density of the electric heating rod is calculated to be 2.52kW/m according to the volume heat release power density of 2.0MW/m 3 and the length of the arranged electric heating rod, and the process is mature for the electric heating rod with the diameter of 4 mm. If the calculated linear power density is too high to manufacture the electric heating rod, the diameter of the electric heating rod is required to be increased (the maximum diameter does not exceed the average particle size of the particle bed), or the arrangement interval is reduced, the proper arrangement interval and the diameter of the electric heating rod are selected again, and repeated iteration is carried out to obtain the optimal result.
Therefore, the embodiment of the invention realizes isotropy of heat release of the particle bed by adopting the electric heating rod through the heat release structure, so that the volume heat release of the particle bed shows higher uniformity on a macroscopic scale, and the technical problem of nonuniform volume heat release in a local unit in the heat source simulation in the particle bed in the prior art is solved.
The foregoing description of the embodiments has been provided for the purpose of illustrating the general principles of the invention, and is not meant to limit the scope of the invention, but to limit the invention to the particular embodiments, and any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the invention are intended to be included within the scope of the invention.
