摘要：

We introduce a simple model of gas-particle flow in a pipeline, which can be used as a tool in engineering design. A chaotic particle motion due to,the particle-particle and particle-wall collisions is modeled by analogy with the motion of gas molecules. The pressure gradient is calculated as a sum of particles drag forces per unit volume. As a result, the problem of pressure losses is reduced to the solution of one nonlinear algebraic equation. The gas viscous friction losses are found by the Colebrook-White approximation. The model is validated by testing it against the experimental data and other, more sophisticated, models known in the literature.
