Experimental Study of Homogeneously Dispersed Two-phase Critical Flow

Abstract

To verify the principle of the occurrence of the critical flow, a homogeneously dispersed two-phase flow is tactfully realized in an experiment. Air and water are used as fluids of the two-phase flow and water is blown into the gas stream as minute droplets. The concrete critical flow condition is carefully obtained by measuring the thrust of the two-phase flow outside the exit plane of the duct. The critical conditions obtained at the experimental result are well coincident with the theoretical ones. At the same time the factors governing the critical conditions of the homogeneously dispersed two-phase flow are also made clear.
