【Abstract】 The optical-electrical measurement is an effective and feasible way to measure solid particle concentration and velocity in gas-solid two phase flow. It can real-time and repidly measure partial soild particle concentration and velocity in CFB. The profiles of velocity and concentration along height and at some cross-section of experimental column in CFB are studied as well.更多还原
