通过激光多谱勒测速仪对搅拌槽内三维流场的测量，定义了具有三维意义上的总体泵送能力系数，并提出了由切向速度定义的泵送能力系数的概念，这些量较初始泵送能力系数和循环流量更能真正反映搅拌槽内的流动和混合。
By measuring the three-dimensional flow field in a stirred tank by a laser Doppler velocimeter, the overall pumping capacity coefficient in a three-dimensional sense is defined and the concept of the pumping capacity coefficient defined by the tangential velocity is proposed, which is larger than the initial The pumping capacity factor and circulating flow more truly reflect the flow and mixing in the agitation tank.
