Number of Papers published in peer-reviewed journals: Number of Papers published in non peer-reviewed journals: A Study of Supersonic Compression-Corner Interactions using Hybrid LES/RANS Models Report Title This research has developed a new hybrid large-eddy /Reynolds-averaged Navier-Stokes turbulence closure strategy specifically designed for strongly interacting, wall-bounded flows. The mode...

Sweep is a feature of all modern wings. Relatively low sweep is used predominantly at moderate speeds, while large sweep is appropriate to high-speed flight. In both cases, a high angle of attack provokes separation, often from the relatively sharp leading edge. The nature of the separation process and the flow structure depend sensitively on the sweep: at low sweep, closed recirculation zones ...

The present work focuses on the comparison of numerical simulation sheet/cloud cavitation with Reynolds Average Navier-Stokes and Large Eddy Simulation(RANS LES) methods around NACA0012 hydrofoil in water flow. Three kinds turbulence models—SST k-?, modified SST Smagorinsky’s model—were used this paper. unstable sheet cavity periodic shedding were predicted, results, namelycavitation shape, fre...

Accurate computational fluid dynamics (CFD) simulations of the ventilation flow in airplane cabins are important for design optimisation regarding passenger health, thermal comfort and energy efficiency. The complex unsteady phenomena inside cabin challenging numerical modelling therefore dedicated validation simulation outcomes is required. majority studies performed steady Reynolds-averaged N...
