High pressure gas quenching process is simulated by computational fluid dynamics (CFD) method. A transient three-dimensional model of high-pressure gas quenching furnace is established on the FLUENT platform to simulate the gas flow in the furnace and cooling of the workpieces. Cooling curves of workpieces at different locations of the furnace are predicted. The simulation results are compared with the experimental ones. The effect of various parameters such as gas pressure, velocity, gas type and gas inlet temperature, on workpieces’ cooling rate was quantitatively studied.
Summary: A transient three-dimensional model of high-pressure gas quenching furnace is established on the FLUENT platform to simulate the flow field in the furnace and temperature field of the workpieces. Cooling curves of workpieces at different locations of the furnace are predicted. The simulation results are compared with the experimental ones. The effect of different kinds of parameters on workpieces’ cooling rate was quantitatively studied.
