ABSTRACT

A closed system of probability-averaged differential equations of dynamics for a one-dimensional isothermal flows of suspensions of matter in gas in pipes has been constructed and solved numerically. It has been established that, under relatively high working pressures in a pneumotransport system, the flow parameters of the suspension vary smoothly along the flow, which allows one to increase the length of a transport pipeline up to hundred kilometers. It is shown that, in principle, it is possible to design pneumotransport systems for pumping mixtures of finely dispersed solid materials and various gas-carriers for long distances.
