中文摘要：
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.
英文摘要：
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.
