CFD study of double entry volute in automotive turbocharger

In this project, behavior of a symmetrical twin scroll voluteand a dual entry volute has been investigated numerically. Acombination of the volute and a turbine is built and thethree-dimensional fluid flow domains have been simulatedby steady state regime. In both case of study, theperformance of the radial turbine is analyzed withcompressible flow and fully three-dimensional viscousassumption. Computational results compared and differentperformance parameters are evaluated by applying anappropriate turbulence model inside the turbine. In order todescribe the turbine performance, the non-dimensionalparameters plotted under the same variable boundarycondition. Furthermore, efficiency and power diagramsdemonstrated and also pressure distribution depicted forwhole passage.
