Abstract

A new method is described for measuring the average void fraction of a one-component two-phase flow moving in a channel with a fixed porous aggregate. The known method of cutting off the flow is used but, in contrast, the vapor phase in the cut-off volume is transferred to the condensed state, and the released space is filled with the measured amount of additional fluid. The result of verification using this method is presented for the previously proposed formula for calculating the void fraction of the adiabatic steam-water flow in a channel with a fixed bed of spherical particles.
