Numerical Simulation and Ezperimental Study of Flow and Temperature Fields during Vacuum High-Pressure Gas Quenching
High-pressure gas quenching is the heat treatment technology which quenches the workpieces by use of high-pressure and high-speed flow gas. In this paper, finite volume method is adopted to numerically simulate the complex gas-solid coupling flow and heat transfer in the vacuum high-pressure gas quenching vacuum. By FLUENT software simulation, the gas flow field distribution and the workpieces temperature distribution are attained. The flow field distribution indicates that in the corner of furnace large whirling current appears and gas resorts for a long time, which is disadvantageous to cool the workpieces here. The workpieces temperature distribution shows that the temperature field of workpieces is mainly affected by the gas flow field Finally the simulated results are contrasted with actual ones. It shows that the experimental time is longer than simulative time and the error is 7.9％.
