Flow over SHM1 Airfoil
The flow over SHM1 at zero angle of attack (Re=10.3 million) attains statistical steady state, separation bubbles are generated and convected near the trailing edge as shown in animation below.

Methods/Schemes used in computations
• For high Re flows, a wide band of scales are excited. To control aliasing error arising out of convection terms, dominant at higher wave numbers, dissipation is added via upwinding the convection terms and by explicitly filtering the solution after every time step using sixth order composite filter [Sengupta et al. (2009)].
Effects on adding FST
Free-stream turbulence is omnipresent in all fluid flows, so its important to include its effects in simulations. Here FST is modelled as described by Sengupta et. al. (2006)
