Abstract

Abstract In the two-phase flow of solids and gases, fluctuations in the solid flow often plagues the experimenter or operator. A technique using an expansion volume based on the damping of gas pulsations in one-phase flow is proposed for the two-phase system. The resulting formulation was applied to actual tests on a coal—air flow system and tests show that the damping of the coal—flow fluctuations were achieved, which are in agreement with the theory. This pipe expansion arrangement is suggested as a technique to smooth two-phase flow system operations.
