Measurements of Flow Rates and Particle Concentrations in Heterogeneous Solid-Water Two-Phase Flows by means of a Venturi

Abstract

In order to establish an accurate measurement method of flow rates Q and particle concentrations C_v in heterogeneous solid-water flows, the discharge coefficients of the Hershel venturi are carefully investigated in both horizontal and vertical arrangements for six kinds of solid-water flows for various Q and C_v. The results shown in simple formulas indicate that the Venturi is an accurate meter for spherical particle-water flows.
