Glove Box Fluid Simulation And Experiment Research

Nuclear fuel generally has matter of radioactivity and toxicity. In order to ensure the safety of nuclear fuel production, people often use the glove box to make it airtight and isolated. In the actual operation of the glove box, the aerosol will stick to the wall or the solid material will deposite at the bottom, due to the unreasonable inlet and outlet position, the air volume and air distribution is not ideal.Based on the numerical simulation and experimental research of the gas in the cabinet, it is aimed at solving the unsatisfied air distribution in the glove box, improving the economy and the optimizing design. Using the Standard k-ε model of Fluent software to simulate five types of flow condition, combined with the experimental measurement area, we can get the output value of numerical results. In order to verify the correctness of the numerical simulation, a set of experimental platform for the flow field in the glove box was set up. Use particle image velocimetry (PIV) to measure the fluid in glove box, and output the experimental measurements. We compared the numerical simulation results with experimental results from the aspects of the trend of the fluid flow, flow direction and speed, ensuring numerical simulation of mathematical model selection, basic hypothesis and boundary conditions set is reasonable. According to the verified numerical simulation method, we set the air age and the air uneven degree as the glove box air distribution optimization objective function for the glove box design optimization. By adjusting the pipe diameter and the location of the inlet and outlet, optimizing the fluid numerical simulation of the cabinet, we know the optimized inlet and outlet position of the simulated air age and air uneven degree.To find out the influence degree and law of the location change to the air age and air uneven degree, we changed the position of the different direction of air current and analyzed its sensitivity. The analytical results can be reference for the future design. The optimized plan for the glove box is finally given after the optimization of numerical simulation. What’s more evenness in the glove box is decreased by 26%.
