Numerical analysis of flow field and temperature field of atomizing gas quenching process

In order to understand the distribution of flow field inside the quenching equipment and the temperature changes of quenching workpiece in the process of quenching,a numerical analysis of atomizing gas quenching process of the workpiece is conducted using computational fluid dynamics(CFD) method.On the Fluent platform,a two-dimensional non-steady-state model of the atomizing gas is built to simulate the distribution of the flow field and the workpiece temperature field in atomization gas quenching equipment,and simulate the impact of fluid type and fluid speed on the cooling rate of workpiece in the quenching process,and also study the impact of the workpiece position in the quenching zone on the cooling curve of the workpiece.Comparison on the simulation results and experimental results shows that the workpiece position in the quenching zone affects the quenching effects under the same conditions.The simulation results provide a useful basis for the optimization of the atomizing gas quenching process.
