Economic Transport Velocity of Gas-Solid Two-Phase Flow in Horizontal Pipe.

Abstract

In this paper the fluid velocity at the point at which the transport power consumption per unit length of the solid-gas two-phase flow becomes minimum, called the "economic transport velocity", is examined from the viewpoint of low power consumption. An empirical equation to predict the economic velocity is first derived for an established flow in a horizontal pipe. Second, the experiment on the economic velocity of coarse particles for the flow was conducted. The foregoing equation is sufficiently accurate for the experimental data, and useful for the approximation of any particles resembling those in the above experiment.
