On the reliability of reynolds-averaged navier stokes prediction of mean flow characteristics of a rectangular turbulent jet in crossflow (2014)
Journal Article

© 2014 Khali and Yao. A jet of fluid discharging into a cross stream, also known as Jet In Crossflow (JICF), has received many experimental and numerical investigations. In addition to the fundamental understanding of three-dimensional mixing and she...

Direct numerical simulation of supersonic flows passing a backward step (2014)
Presentation / Conference Contribution

The Mach 2.9 supersonic turbulent flow over an expansion-compression corner with a sharp deflection angle of 25° at three Reynolds numbers Re_δ=20000, Re_δ=40000 and Re_δ=80000 were studied by using a recently developed direct numerical simulation (...

Investigation of low-dissipation monotonicity-preserving scheme for direct numerical simulation of compressible turbulent flows (2014)
Journal Article

© 2014 Elsevier Ltd. The influence of numerical dissipation on direct numerical simulation (DNS) of decaying isotropic turbulence and turbulent channel flow is investigated respectively by using the seventh-order low-dissipation monotonicity-preservi...

Direct numerical simulation of supersonic turbulent flow in an expansion-compression corner at mach=2.9 (2014)
Presentation / Conference Contribution

Shock-wave/turbulent boundary layer interactions (SWTBLI) are prevalent phenomena in high-speed flights, which could cause large flow separation and high wall heat flux and strong pressure fluctuation, therefore, affect significantly the aero-thermod...

Numerical simulations of two-dimensional and three-dimensional shock wave/turbulent boundary layer interactions (2014)
Presentation / Conference Contribution

The impinging shock-wave/flat-plate boundary layer interaction is a standard CFD case for two-dimensional (2D) SWTBLI, which represents the simplest SWTBLI configuration for the validation of turbulence models and computational methods. Although plen... Read More about Numerical simulations of two-dimensional and three-dimensional shock wave/turbulent boundary layer interactions.

Direct numerical simulation of a turbulent flow over an axisymmetric hill (2014)
Journal Article

Direct numerical simulation (DNS) of a turbulent flow over an axisymmetric hill has been carried out to study the three-dimensional flow separation and reattachment that occur on the lee-side of the geometry. The flow Reynolds number is Re H=6500, ba... Read More about Direct numerical simulation of a turbulent flow over an axisymmetric hill.

Modelling conjugate flow and heat transfer in a ventilated room for indoor thermal comfort assessment (2014)
Journal Article

Conjugate natural and forced convection heat transfers in a domestic model room of finite-thickness walls and a heat source have been numerically studied. A 2-D non-ventilated square model room with a heat source is investigated at first for conditio...
