Multi-block high-order dns code development for jet in turbulent cross-flow simulation (2012)
Journal Article

A multi-block high-order finite-difference direct numerical simulation (DNS) code has been developed for studying turbulent flows over complex geometries. A global mapping technique is adopted and applied to a multi-block domain arrangement, in which...

Numerical simulation of a turbulent flow over an axisymmetric hill (2012)
Presentation / Conference Contribution

Simulation of a turbulent °ow over an axisymmetric hill has been carried out to study three-dimensional °ow separation and reattachment that occur on the lee-side of the geome-try. A total of four simulations are considered at low Reynolds number of... Read More about Numerical simulation of a turbulent flow over an axisymmetric hill.

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 and secondary separation modelling at crossing shock wave/turbulent boundary layer interaction conditions (2012)
Journal Article

Steady RANS modelling has been carried out for a symmetrical double-sharp-fin configuration with an inclination angle 15°, Mach 3.92 and Reynolds number Reδ = 3.08 x 105. Grid refinement and turbulence model influences using ω-based Reynolds Stress m...

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.

Shock induced separating flows in scramjet intakes (2012)
Journal Article

Shock induced separating flows in a scramjet intake has been studied by using a computational fluid dynamics approach. A configuration of scramjet intake geometry consisting of two exterior compression ramps, followed by a subsequent inlet and interi...
