The Construction And Analysis Of Temperature Field In ICF Driver's Target Building

At present, people has realized the energy crisis ponderance increasingly, has been making great efforts to explore a new, clean, abundant energy therefore. Controlled nuclear fusion reaction fuels are deuterium and tritium mainly, and deuterium, tritium fuel can be extracted from the water, the fusion energy being used to come into being from the deuterium that a liter water extracts in is that 70 liters of petroleum burn the energy coming into being about. There is a lot of water on Earth, it can be said to be a fusion inexhaustible energy, but also a clean and safe energy, and can be cheaper than fission.At present, in the world, the main developed country already builds or constructs Inertial Confinement Fusion(ICF) solid state laser, which as an important indicator of national security, energy and of the level of scientific research. The temperature is outstanding gradually and being taken seriously in being that ICF solid state laser stability a working key factor, and the temperature at present in high power solid state laser prototype target building is highlighting in China, the paper studies the key part of high power solid state laser prototype devise—the middle layer, analyses the flow and heat transfer situation under the Heating Ventilation and Air Conditioning (HVAC).According to the needs of application, the paper combines the actual building structure of ICF high power solid state laser prototype target building middle layer, and numerical simulation theory, analyses the control equations' and calculating region' discretemagnitude with finite volume method, summing up the numerical-control equations and boundary conditions of the model. Multi-channel PC-2WS temperature monitoring recorders and PTWD-2A precision temperature sensors are used for 4 vertical cross-section and walls of the middle layer temperature experiment, the data have been handled by MATLAB, then we obtain the approximate flow and heat distribution of the target building (Innovation, Chapter3). A stable three-dimension numerical calculating model is established, which takes the radiation effects into account .The FLUENT software is used to simulate the heat transfer situation with boundary conditions which are the walls' temperature from the experiment, and analyses the heat distribution of the target building particular(Dominating Innovation, Chapter2,4). The simulation results and experimental results are compared. Good agreement between them shows that's the computes distribution of temperature can supply warrants for optimized designing of the ICF high power solid state laser prototype target building.
