Numerical Simulation of Flow Past Elliptic Cylinder Using Smoothed Particle Hydrodynamics

Abstract

The flow past bluff bodies is a fluid–structure interaction problem that has both fundamental and research interests in the field of computational fluid dynamics. The flow past bluff bodies with circular and square shaped cylinders have been studied extensively in the literature. However, limited studies are reported on flow past elliptical cylinders, even though they are preferred in many practical applications due to smaller wake region and drag coefficients. In this work, we develop a numerical model using meshless particle method known as smoothed particle hydrodynamics to analyse the fluid-structure interaction of a stationary elliptic cylinder in a steady viscous fluid flow for Reynolds numbers varying from 10 to 60. Qualitative comparison of the obtained results shows good agreement with the existing results in the literature. We believe that the developed model can be further extended to investigate the fluid dynamics of more complicated problems involving movable and deformable objects. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
