CFD prediction and experimental measurement of blade water coverage in a diesel turbocharger (2012)
Journal Article

A turbocharger unit for diesel engine is often equipped with a built-in online water washing system and its performance is not always satisfactory because of efficiency declination due to deposit accumulated on blade surfaces not being washed away. I... Read More about CFD prediction and experimental measurement of blade water coverage in a diesel turbocharger.

Effect of jet inclination angle and hole exit shape on vortical flow structures in low-reynolds number jet in cross-flow (2012)
Journal Article

Numerical studies have been performed to visualize vortical flow structures emerged from jet cross-flow interactions. A single square jet issuing perpendicularly into a cross-flow was simulated first, followed by two additional scenarios, that is, in...

Flow topology of symmetric crossing shock wave boundary layer interactions (2012)
Book Chapter

Three-dimensional crossing-shock-wave and turbulent boundary-layer interactions can generate intense wall heat flux rates, high pressure levels, and large-scale flow separations on high-speed vehicle surfaces. To reproduce such complex flow physics,... Read More about Flow topology of symmetric crossing shock wave boundary layer interactions.
