Modeling Operating Regimes in Multiphase Flowmeter Flow Path Using CFD Methods

The object of this study is multiphase flowmeter flow path and the processes occurring along the axis of the flowmeter. the Venturi tube, designed to measure the volumetric rate flowing therein medium using differential pressure, is considered as a measuring means. Based on the results of numerical solution of equations for steady turbulent flow of compressible multiphase flow the accuracy of measurement of pressure along the axis measuring part of the Venturi tube and the pressure unit is estimated, and also the flow of multiphase medium is considered.
