Numerical Investigation on Improvement of Flow Field Structure in Large Quench Tank
According to the major design deficiency of the existing tank,the computational fluid dynamics (CFD) technique is adopted to simulate the flow field in the large quench tank,and two optimum schemes are brought forward.Further more,the influence of different mixer systems on the flow field in the large quench tank is analyzed.Simulation Results show that the non-uniform flow field is generated throughout the quenching zone in the existing large quench tank,and the flow rate of the quenchant is rather low,which may lead to the workpiece insufficient and non-uniform cooling rate.Setting an inner core in the center zone of the tank increases the flow rate in the region near the inner surface of workpiece.Using the submersible impellers,the flow of the quenchant in the region near the outer surface ofworkpiece significantly strengthened.There is parallel relation between the flux of the inner core and that of the submersible impeller.
