Characterization of a radial turbocharger turbine in pulsating flow by means of CFD and its application to engine modeling (original) (raw)

Abstract

h i g h l i g h t s " CFD simulations of a variable geometry turbine under steady and pulsating flow. " Most accumulations effects occur in the volute which also averages pressure pulses. " Flow detachment around the nozzles blades leads to hysteretic effects in the stator. " Rotor flow capacity is quasi-steady, but torque depends on the inflow conditions. " A simple turbine model is proposed and agrees well with the CFD results.
