Optimization of the Inlet of the Online Metering Instrument for Oil-water Two-phase Flow Based on Phase State Regulation
Aiming at the influence of the inlet flow pattern of the phase control measuring device on the parameter measurement of oil-water two-phase flow,taking the inlet flow patterns of three inlet forms,namely radial single inlet,radial double inlet and tan-gential double inlet,as the research objects,theoretical analysis and numerical simulation were carried out on three phase control measuring devices with different inlet structures by using the Realizable k-ε model and fluid volume multiphase model in Fluent simulation software.The results show that the inlet flow pattern with tangential double inlets can reduce the inertial impact of the inlet fluid,reduce the turbulent pulsation in the inlet area,restrain the uneven distribution of the flow field caused by the falling of the inlet fluid,and reduce the short-circuit flow and circulating flow at the lower outlet.
