A 3D fluid-structure interaction (FSI) code is under development. The fluid domain (Navier-Stokes) solver will employ a sharp interface ghost node immersed boundary method (IBM) to apply the boundary conditions at fluid-solid interfaces. The Navier-Stokes (N-S) solver has been verified using a classic Poiseuille channel flow. The current version of the immersed boundary method is being tested by solving a heat conduction problem. The order of accuracy of the IBM was shown to be just above second order.

In this paper, academic and industrial test cases have been conducted in order to validate the approach of using a Penalized Direct Forcing method coupled with an immersed turbulent wall model. Good results are obtained compared to a body fitted mesh with the Werner & Wengle wall model. In a shortcoming second step, we can project the coupling between the immersed wall law and a K-epsilon model, as well as obstacle shape optimization during the flow computation.
