1. Challenging water wakes studies of breaking waves, where a two-phase LES in-house code has been developed, achieving for the first time stable and accurate simulations for high Froude numbers (above one) for free surface piercing cylinders (Yu. et al, J Fluids Eng 2008, Avital J. Comp Acou. 2009). This was accompanied by the development of DES code coupled with the immersed boundary method to simulate high Reynolds water flows around submerged bodies (Ikarm et al, J. Fluids Eng 2012)
3. Tidal energy: LES computation of a tidal turbine using a combined approach of LES with Discrete Element Method (DEM) to investigate turbulent flow around single and dual rotors and improve computational efficiency of pressure solver and grid resolution carried out with the support of the Royal Academy of Engineering and collaboration with Atlantis Resources Corp (Bai et al, Ren. Energy 2014)
4. Drag reduction: Development of Micro-vortex generator expertise to reduce pressure drag for underwater vehicles with the support of UK dstl.
