摘要： 将粒子成像测速(PIV)技术应用于旋转盘反应器，获得了旋转盘表面流场的瞬时速度分布，研究了操作参数(流量和转速)对流场速度分布的影响. 结果表明，从盘中心到边缘瞬时速度先减小后增大；转盘中心区域的速度场主要由流量控制，流体的相对径向速度随流量增大而增大；转盘外缘区域的速度场主要由转速控制，流体的相对周向速度随转速增大而增大；实验条件下临界半径Rc=50 mm，转盘设计半径应适当大于临界半径.

Abstract: Particle image velocimetry (PIV) was applied to a spinning disc reactor, the instantaneous velocity distributions of flow filed on the spinning disc were obtained, and the effect of rotational speed and flow rate had been discussed. The experimental results revealed that the instantaneous velocity is firstly decreased and then increased from center to edge of the disc. The velocity field on disc center is controlled by flow rate, relative radial velocity increases with increasing flow rate. The velocity field on disc edge is controlled by rotational speeds, relative circumferential velocity increases with increasing rotational speeds. In the range of experimental conditions, critical radius (Rc) is about 50 mm, disc radius should be larger than Rc, appropriately.

Key words: particle image velocimetry, spinning disc reactor, flow field, velocity distribution
