An improved immersed boundary method for turbulent flow simulations on Cartesian grids

In this paper, we present recent improvements of an Immersed Boundary Method (IBM) for the simulation turbulent compressible flows on Cartesian grids. The proposed approach enables to remove spurious oscillations at wall skin pressure and friction coefficients. Results are compared a body-fitted using same function, showing that stair-step immersed boundary provides smooth solution one. method has been modified adapt location forced forcing points involved in reconstruction Reynolds number. This validated either subsonic transonic flow regimes, through around NACA0012 profile RAE2822 three-dimensional ONERA M6 wing.
