Numerical Simulation of Coal Water Mixture Pipeline Transport Axial Flow Field

摘要

The finite element method is applied to simulate the coal water mixture pipeline transport axial flow field. The pipeline axial velocity and contour distribution are obtained by solving the divided pipeline axial flow field. The relationship curves between the axial velocity and the cross sectional radiuses of the pipeline axial flow field are drawn. Two groups of comparative computations are performed and the relationships between the axial velocity and the variety of the axial pressure gradients and cross sectional radiuses are indicated according to the conclusions. The average axial velocity and the maximum axial velocity are compared. According to the comparison results, a method of calculating the flow quantity of the pipeline is obtained.
