In order to improve turbocharger turbine performance,the design and experimental research on mixed-flow turbine for the JP78B turbocharger that matched a certain diesel engine were carried out.For the eight designed mixed-flow turbine rotors,the interior flow of rotor was computed with the computational fluid dynamics(CFD) software called NUMECA,and the influence of inlet inclined angle,inlet incidence,axial chord and blade number on rotor performance of mixed-flow turbine was analyzed.The performance exper...
