|Abstract:||A study on flow over bluff bodies is a prime research problem in mechanical engineering since it helps to understand various fluid dynamics characteristics. This is a fluid–structure interaction problem which makes it challenging and complex. This paper discusses the development of a computational model to simulate the viscous flow over an elliptic cylinder. In this paper, a feedback forcing-based immersed boundary method coupled with Dirac delta function is used to construct the model. Also, two coordinates systems are employed—Lagrangian (for elliptic cylinder) and Eulerian (for fluid flow). Initially, the developed numerical model is validated. Later, the flow behavior for a fixed aspect ratio of the elliptic cylinder is studied for different Reynolds numbers. It can be seen that steady symmetric flow pattern is obtained for the range of Reynolds numbers considered in the present study. © Springer Nature Singapore Pte Ltd. 2019.|
