根据在浓相输送情况下气／固混和物流经文丘里管时的流动特性，建立了水平管内（ｋ＝１时）空气和煤粉连续流动的分相流模型该模型提供了通过使用文丘里管和电容传感器测量混合物的差压和固相浓度来推导固相速度和质量流量的新方法 Based on the flow characteristics of the gas / solid mixture and the flow through the venturi under dense phase transport, a split-phase flow model was established for the continuous flow of air and pulverized coal in the horizontal pipe (k = 1) New Method to Derive Solid Phase Velocity and Mass Flows by Measuring Differential Pressure and Solid Phase Concentration of Mixtures in In-tube and Capacitive Sensors
