Tests on flow resistance characteristics of gas-solid two phase flow in pipes were performed on a 1:1 scale industrial pneumatic conveying system test rig. 在1∶1比例的工业气力输送系统试验台上,进行了输送管道中气固两相流的阻力特性试验,对影响气固两相流压力损失的主要因素,包括被输送物料的基本性质...
Such kind of two-phase flows is termed as "dispersed flows" where individual particles are more or less homogeneously distributed in the continuous phase (i.e., gas or liquid). In dilute dispersed systems, the particle transport is governed mainly by fluid dynamic forces acting on the particle...

We present a numerical investigation on the two-dimensional, dilute gas-particle two-phase flows passing a circular cylinder at high Reynoldes number. 基于离散涡方法(DVM)求得的非定常不稳定流场和颗粒的Lagrange运动方程,数值模拟了高雷诺数下的气固两相圆柱绕流,结果证明了气固两相流动中颗粒运动与流体...
The aforementioned airflows carried dust to the space around the driver through three path types including from the heading face, along the roadway floor left of the road-header, and by refluxing from the rear of the road-header. The dust concentration in front of the driver was observed to...
Results show that for any one of those two input values, the correct rates of the ANN model are all 100%. Keywords: electrostatic sensor array; artificial neural network; gas-solid two-phase flow; flow pattern identification 1. Introduction Flow pattern identification of gas–solid two-phase ...
It was concluded that: 1) The mixture model was successfully applied to simulate the turbulent particle-gas two-phase flows in an impeller blower, and predict the conveying property of the impeller blower. 2) Impellers with 4 paddles were more favorable for throwing/blowing materials than 3 and...
The paper presents a review of theoretical and experimental works devoted to two-phase (gas-solid) flows past bodies. The particularities of particle motio
The gas- solid two-phase flows of the precalciner were simulated by different multiphase models, such as mixture model, the Eulerian model, including mixture and dispersed, and discrete phase model (DPM). The results of the different multiphase models were analyzed and compared, showing the ratio...
5) dense liquid-particle two-phase flow 稠密固液两相流 1. A new formula for evaluating the mean velocity gradient G of dense liquid-particle two-phase flow in pipes was derived based on the mixing length theory of turbulent flows, which proved valid for the hyper-concentrated turbulent flow...
