摘要： 由于气/固两相流本身具有复杂的流动形态,从流体力学角度分别建立了下行管道传送、上行管道传送和水平管道传送的固相质量浓度的表达式.结合静电传感器互相关技术测量得到气/固两相流的速度参数,根据固相质量流率计算公式和固相质量浓度的表达式,完成了气/固两相流固相质量流率的间接测量.

Abstract: In view of the complex flowing states of gas-solid two-phase flow, the expressions of solid mass concentration relevant to the two-phase flow were deduced on the basis of fluid mechanics when the flow is in the up, horizontal or down conveying pipeline. Then, with the measuring technique on the principle of cross-correlation used to measure the velocity parameter, an indirect measurement was done for the mass flowrate of gas-solid two-phase flow according to the formula of solid-phase mass flowrate and the expression of mass concentration.
