【Abstract】 In order to investigate the flow rate distribution and improve the flow uniformity of the quenchant in quench tank, the ultrasonic Doppler velocimeter was adopted to measure the flow rates under agitation. The fluid dynamic was also simulated by the finite element method. According to the results of computational fluid dynamic,the position of flow baffles of quench tank was optimized. The results show that the ultrasonic Doppler velocimeter is suitable to measure the flow rate of quench tank in large size.It is possible to refer to the results of computational fluid dynamic to design the quench tank with improved flow uniformity.更多还原
