Pressure drop measruement in two-phase pipe flow and two-phase pump flow

摘要

This paper presentes an experimental study on pressure drop properties in air-water two-phase pipeflow and pump flow.The pressure drop of a two-phase flow is measured by silicon-resistance-difference-pressure type pressreu sensors and signal processing circuits in the test-loop on a section at locations of 0 deg,90 deg,180 deg,and 270 deg respectively under various flow patterns.The measurement rexsults of difference pressrue at the entrance and exit of two kinds of typical booster pumps: centraifugal pump and jet pump under different flow patterns by using strain diaphragm-pressure-transducers are also presented in this paper.
