I am a Research Assistant at Polytechnique Montréal, advised by Prof. Jean-Yves Trépanier and Prof. Sébastien Leclaire. I have 5+ years of working experience on numerical simulations. I have developed a numerical solver for compressible flows using Immersed Boundary approach for moving geometries as a part of Master's thesis. The project is in collaboartion with General Electric Grid Solutions, France for developing a numerical solver for High Voltage Circuit Breaker.

Immersed Boundary (IB) methods have been successfully implemented for different applications including moving as well as stationary geometries. One of the problems in IB method implementation for moving boundaries is the conversion of solid cells to fluid cells. In order to solve this problem, mainly two different groups of methods are available. The first group of methods relies on extrapolating the variables on the adjacent solid cells and the second group deals only with the interpolation in the fluid region. This paper draws a comparison between the two approaches for compressible inviscid flows and discusses, in detail, which method is suitable for what kind of application.
The present method preserves the simplicity of sharp interface immersed boundary method and hence avoids complex coding logistics. This method uses a dynamic search algorithm for tagging of the immersed nodes and reduces the computational overheads. Mass conservation is ensured in the intercepted cells through a hybrid SOLA–MAC algorithm.
A computational study of flow over an airfoil, NACA 0012, is performed using the Immersed Boundary Method at chord Reynolds numbers of 5300. Lift Coefficients are calculated for different angles of attack and compared with the experimental results (Mahbub-Alam et al., 2010).
