At present, boiling heat transfer technology has become the cutting-edge technology of heat transfer, and under the interaction of electric field, flow field and temperature field, the mechanism of its enhanced heat transfer is very complicated, and there are many influencing factors, among which the electric field distribution is the most important factor affecting the boiling transfer. Heat is a very important factor, but the current theoretical research work is still in the qualitative analysis, so it is not yet possible to determine the optimal design scheme in engineering
[0003] In heat transfer technology, the heat transfer of the medium in two phases, which is called latent heat transfer, has great advantages over traditional heat transfer, and has received great attention in engineering. However, the characteristics of two-phase fluids are in Theoretically still in the qualitative stage

The equipment comprises a closed box body for accommodating a fluid medium, a heating device used for heating the fluid medium to form a mixed fluid which has a steam phase and a liquid phase and is positioned above the liquid level of the fluid medium, and a counting and measuring device used for measuring the volume occupancy of the steam bubbles in the mixed fluid, wherein the heating device is arranged in the box body, a runner through which the mixed fluid passes is formed in a space, above the liquid level of the fluid medium, in the box body, and the counting and measuring device is arranged on the outer side of the runner. The equipment and the method disclosed by the invention realize application to the engineering, and are simple and convenient to operate.
Description
technical field [0001] The invention relates to the technical field of enhanced heat transfer, in particular to a measuring device and method for the volume ratio of vapor bubbles in two-phase fluids. Background technique [0002] Enhanced heat transfer is a new type of heat transfer technology, which uses the interaction of electric field, flow field and temperature field to enhance heat transfer. At present, boiling heat transfer technology has become the cutting-edge technology of heat transfer, and under the interaction of electric field, flow field and temperature field, the mechanism of its enhanced heat transfer is very complicated, and there are many influencing factors, among which the electric field distribution is the most important factor affecting the boiling transfer. Heat is a very important factor, but the current theoretical research work still stays on qualitative analysis, so it is still impossible to determine the optimal design scheme in engineering. ...
