Investigation Of Temperature Distribution And Numerical Simulation Of Heat Exchanging Of Uniform Inner Heat Source Liquid In Column-form Liquid Pool

The exploitation of nuclear energy is one of the most important dispositions in our country. But the nuclear rubbish produced by the nuclear reactor, which is to do harm to the people and environments and also waste the remain disintegration energy, is hoped to be well disposed. People did the researches to solve the problem of using the disintegration energy and reduce the nuclear pollution long time ago. The subject of using the disintegration energy to produce the isotopes of 99Mo and 131I in medicine is having huge economical benefits and important meanings to the environments. The using mold is having good economical benefits, friendly to the environment and easy to achieve, so is used extensively by the USA, Russia and Canada etc. The liquid solution is used for nuclear fuel in the solution reactor. The solution in the reactor has uniform inner heat source, and there are tiny air bubble built, the whole system is running by natural convection and the driving of air bubble. The gas-liquid two phase flow and heat transfer are mutual effecting to become the complex pyrology system. At present, there are few researches in domestic. In this text, the studies of uniform inner heat source, the temperature distribution and heat transfer characteristic of produced gas-liquid in the cylindrical container are made with both experiment method and numerical simulation. And this work provides some references for the design of solution reactor and security analyze.The experiment studies the temperature distribution and heat transfer characteristic of produced gas-liquid in the cylindrical container when there are natural convection and gas-liquid two phase flow.Build the mathematical and physical mold of heat transfer for the natural convection and bubble driving in the solution of uniform inner heat source. The numerical simulations of the cold field in the solution of inner heat source are made. And the natural convection flow field, temperature distribution, the rule of heat transfer and the flow field, temperature field and the heat transfer rule of the gas-liquid two phase flow are studied for the situation of single heat transfer pipe. The most effecting field of the cold field in difference working situations are studied, and provided the reference of the flow of cold water using for guarantee the temperature of the solution is...
