摘要: Purpose – The purpose of this paper is to study the effects Angle Attack (AOA), Axis Ratio (AR) and Reynolds number (Re) on unsteady laminar flow over a stationary elliptic cylinder. Design/methodology/approach governing equations fluid cylinder are solved numerically Cartesian grid using Projection method based Immersed Boundary technique. This numerical validated with results available in open literature. scheme eliminates requirement generating new computational mesh upon varying any geometrical parameter such as AR or AOA, thus reduces time cost. Findings Different vortex shedding patterns behind identified classified averaged centerline streamwise velocity profile, instantaneous vorticity contours streamline patterns. A space graph constructed order reveal dependence AR, AOA Re shedding. Integral parameter...
