Description
Technical field
The invention belongs to flow boiling visual research fields, and in particular in a kind of Rectangular Narrow Channel of bidirectional visual
CHF studies visual experimental apparatus.
Background technique
Critical heat flux density CHF is the heat transport limitation of flow boiling, accurately predicts critical heat flux density value to reactor
Design and accident conditions under operation be of great significance.Planar fuel assemblies with Rectangular Narrow Channel feature are because having knot
The advantages that structure is compact, fuel pellet temperature is low, heat exchange area is big is widely used in research experiment heap and integral reactor
In.Predict that some rule-of-thumb relations of critical heat flux density are all based on oneself fitting experimental data in existing Rectangular Narrow Channel
It obtains, accuracy is strongly depend on the similitude of experiment condition, can not be generalized to other operating conditions.So the direction of research exists
The characteristic of two-phase and steam bubble behavior, establish prediction model when observing critical by visual research.Traditional visualization device
Rectangularl runner is formed by the way of a face metal and face transparent window compacting, is powered to metal side runner and utilizes the heat of resistance
Effect is heated to fluid, and obtains runner outside wall temperature in metal heater plate outer surface welding thermocouple.This device exists
Runner side is not visible, and runner gap is unable to accurately control, processing difficulties, it has not been convenient to the problems such as dismounting.
In the patent document of 102661845 A of Publication No. CN, a kind of disclosed " visual narrow rectangle Natural Circulation system
The visualization heating rectangle experimental section of system " being mainly characterized by up to 1000mm, can intuitively and accurately be recorded in runner
Mobility status.Interim " the water boiling in vertical Rectangular Narrow Channel of " Thermal power engneering " volume 29 the 6th that in November, 2014 publishes
The flow pattern research of heat exchange " refer to the visualization device of narrow rectangular channel single-sided metal heating a kind of.It is mentioned in document above
Although narrow rectangular visualizations experimental provision can satisfy observing and recording for the transformation of convection under certain condition and bubbling behaviour, still
It there are still some drawbacks.Firstly, the rectangularl runner gap that conventional visualization makeup is set is not exclusively controllable.Because of traditional experiment device
Quartz glass is compressed by steel plate and heating plate forms Rectangular Narrow Channel, and compressive stres are from piercing with the bolt and nut on steel plate
It provides.Not can guarantee in installation process all bolts to screw up degree identical, also result in gap at rectangularl runner different cross section
It is different.Secondly, traditional rectangular passage experiment device can only from front shooting bubble polymerization behavior, can not from side bubble
Growth and some important parameters for influencing critical heat flux densities, such as bubble layer thickness, thickness of liquid film.Finally, above-mentioned experiment
The runner gap of device is fixed, and influence of the channel effect to flowing can not be studied.So, if it is possible to invent a set of experimental provision
The above problem is improved, the CHF under Rectangular Narrow Channel can be made to study more safe and accurate.

Heating plate 4 is bigger.Position is machined with the slot of deep 6mm among the boss of matrix, and the width and length of slot are and 4 phase of heating plate
Together.It processes on matrix 11 there are three the through-hole for piercing matrix 11, the diameter of through-hole is more slightly larger than support column 12, pitch-row and support
The distance between column 12 is equal.
With the sealing of Graphite pad 2 with a thickness of 3mm between heating plate 4 and matrix 11.The highest tolerable temperature of Graphite pad 2
Up to thousands of degrees Celsius.
The width and matrix 11 of the broadside quartz glass 5 are identical, and cross section is at recessed in T font, with the wide face of shell 10
Slot cooperation.
The cross section of the narrow side quartz glass 8 cooperates at the groove in T font, with 10 leptoprosopy of shell.
The wide face of 6 width of broadside bearing plate and shell 10 is identical.6 squarely of broadside bearing plate is cyclic annular, and middle section is engraved
It is empty.The width of hollow-out part is identical as runner broadside, and length is identical as the boss of matrix 11.In the circumferential direction of broadside bearing plate 6
10 through-holes are machined with, the threaded hole in spacing and the wide face of shell 10 is away from identical.
9 width of narrow side bearing plate is identical with 10 leptoprosopy of shell.9 squarely of bearing plate is cyclic annular, middle section hollow out.It engraves
The length of empty part is identical as the land length on narrow side quartz glass 8, and width is omited than the projection width on narrow side quartz glass 8
It is long.10 through-holes are machined in the circumferential direction of narrow side bearing plate 9, the threaded hole on 10 leptoprosopy of spacing and shell is away from identical.
It is sealed by fluororubber pad 7 between broadside quartz glass 5 and narrow side quartz glass 8 and shell 10.It can lead to
The thickness for crossing adjustment broadside fluororubber pad 7 changes runner gap.
In conjunction with Fig. 4 and Fig. 5, the assembly method of experimental section is done as described below.
Firstly, ring-shaped graphite gasket 2 is put into the groove on 11 boss of matrix, the through-hole on matrix 11 will be heated
Plate 4 is placed on Graphite pad 2.Heating plate 4 is set to compress Graphite pad using the pretightning force that nut provides.Then, by fluorine rubber
Glue gasket 7 is placed on the groove in the wide face of shell 10, and heating plate 4 is integrally placed on fluororubber pad 7 together with matrix 11, will be wide
Side bearing plate 6 is placed on matrix 11, makes the screw hole centering on the through-hole and the wide face of shell 10 on broadside bearing plate 6.At this point, with
Gap between vernier caliper measurement broadside bearing plate 6 and the wide face of shell 10, is denoted as d0.Then, it will be fastened in diagonal mode
Bolt is screwed on one by one in the screw hole in the wide face of shell 10.Constantly measured during tightening broadside bearing plate 6 and the wide face of shell 10 it
Between gap, be denoted as d.d-d0Just it is equal to the decrement δ of gasket.By prior calculating it can be concluded that when δ is equal to particular value δ0
When, heater plate surface and the face a of 10 leptoprosopy groove of shell can be made concordant with the face c.Then, with same method by two pieces of narrow sides
Quartz glass 8 and broadside quartz glass 5 are fixed on the housing 10, make the upper surface of the boss of two blocks of narrow side quartz glass 8 respectively
It is concordant with the face e of the wide face groove of shell 10 and the face f, the boss upper surface of broadside quartz glass 5 and the leptoprosopy groove of shell 10
The face b it is concordant.When needing to increase runner gap, the thickness of the gasket 7 between broadside quartz glass 5 and shell 10 is increased.
When needing to reduce runner gap, the thickness of the gasket 7 between broadside quartz glass 5 and shell 10 is reduced.Runner gap is most
The greatly width of 8 boss of narrow side quartz glass, minimum 0.Finally, power positive cathode is connected to about 4 support column of heating plate,
Inlet/outlet pipe is connected to lower flange on experimental section.Ensure to carry out in the case that experimental section electrical insulating property and leakproofness are intact
Experiment.
