Abstract: The present work combines experimental measurements and unsteady, three-dimensional computational fluid dynamics predictions to gain further insight into the complex flow-field within an automotive turbocharger centrifugal ...

Abstract: Deep surge is a violent fluid instability that occurs within turbomachinery compression systems and limits the low-flow operating range. It is characterized by large amplitude pressure and flow rate fluctuations, where the ...

Abstract: Stereoscopic particle image velocimetry (SPIV) measurements are carried out at the inlet of a turbocharger compressor at four different shaft speeds from 80,000 rpm to 140,000 rpm and over the entire range of flow rates ...

Abstract: Largeamplitude deep surge instabilities are studied in a turbocharger compression system with a onedimensional (1D) engine simulation code. The system consists of an upstream compressor duct open to ambient, a centrifugal ...

Abstract: Stereoscopic particle image velocimetry is used to characterize the variation of the turbocharger compressor inlet velocity field as a function of rotational speed, with an emphasis on surge. While the velocity magnitudes ...
