according to the basic fluid mechanics equation of the filter, the filter is subjected to mathematical modeling, and the continuity equation of the fluid mechanics is analyzed;
1. the continuity equation is the conservation of mass equation,
any flow problem must satisfy the mass conservation law. According to the law of conservation of mass, the sum of the net mass of the fluid flowing out of the control body in unit time should be equal to the mass reduced in the control body due to density change at the same time interval, so that the differential form of the fluid flow continuity equation can be derived as follows:
in the formula:
the ux, the uy and the uz are respectively velocity components in the x direction, the y direction and the z direction, and m/s;
t is time, s;
rho is density, kg/m3
2. Momentum equation of fluid mechanics
The nature of the momentum equation is to satisfy newton's second law. This law can be described as: for a given fluid infinitesimal body, the rate of change of momentum with time is equal to the sum of the various forces acting on the body from the outside world. According to the law, the momentum equations of the x, y and z directions can be derived as follows:
in the formula:
p is the pressure on the fluid micro-element, Pa;
τ xx, τ yy, τ zz, etc. are components of the viscous stress τ acting on the surface of the microelement due to molecular viscous effects, Pa; fx, fy and fz are unit mass forces in three directions, m/s2
The momentum equation has many expressions in practical application, and the following ones are more common.
(1) Momentum equation of compressible fluid
(2) Equation of momentum for normally viscous fluids
(3) Conservation of momentum equation for constant density viscous fluids
(4) Conservation of momentum equation for non-viscous fluids
(5) Equation of statics
The system of continuity equations and momentum equations for an actual fluid becomes the navier-stokes (N-S) equation.
3. Energy equation of fluid mechanics
The law of conservation of energy is the fundamental law that a flow system containing heat exchange must satisfy, and its essence is the first law of thermodynamics. According to the law of conservation of energy, the rate of increase of energy in a infinitesimal body is equal to the net heat flux entering the infinitesimal body plus the work done by mass force and surface force on the infinitesimal body, and the expression is given as follows:
in the formula:
e is the total energy of the fluid micelle, J/kg, and comprises the sum of internal energy, kinetic energy and potential energy,
h is enthalpy, J/kg, defined as
Wherein Tref is 298.15K;
keffis the effective thermal conductivity, W/(m), keffK + kt, kt being the turbulent heat transfer coefficient, determined according to the turbulent model used;
jj is the diffusion flux of component j;
sh is a heat source term that includes the heat of chemical reactions and other user-defined volumes;
mathematical modeling is carried out through the equation, and two different working conditions of operation and backwashing are analyzed.
Analyzing the operating condition:
1. the calculation result (yz plane) of the operation condition operation for 5min is as shown in fig. 4 (operation condition operation X is 0.98 section flow field) and fig. 5 (operation condition operation X is 7.7 section flow field);
2. operating conditions (operating conditions) for 5min, such as fig. 6 (operating conditions y is 0 section flow field), and calculating results (xz surface);
3. running for 5min under the operating condition (xy plane), as shown in fig. 7 (the operating condition is running in the z-0.575 section flow field), and fig. 8 (the operating condition is running in the z-1.66 section flow field);
and (3) backwashing condition analysis:
1. backwashing for 5min under backwashing conditions (yz surface), as shown in figure 9 (backwashing condition x is 0.98 section flow field) and figure 10 (backwashing condition x is 7.7 section flow field);
2. backwashing for 5min under backwashing conditions (xz surface), as shown in figure 11 (backwashing condition y is 0 section flow field);
3. backwashing for 5min under backwashing conditions (xy surface), as shown in figure 12 (backwashing conditions in z-0.575 section flow field), as shown in figure 13 (backwashing conditions in z-1.66 section flow field);
the results prove that:
under the operating condition, water flow in the equipment is uniformly distributed on the filter layer;
