The fluid flow over a circular cylinder has been studied extensively. On the other hand, literature on the flow over an elliptical cylinder, particularly at low Reynolds number, is limited. Intending to bridge the gap, the effects of axis ratio (0.3 ≤ AR ≤ 1) and blockage ratio (0 ≤ BR ≤ 0.12) were studied by implementing the computational fluid dynamics code FLUENT, using the control volume approach at a Reynolds number of 40 based on hydraulic diameter. For unbounded flow, a circular computational domain having a radius of 40 times the diameter (d) of the circular cylinder was considered. The front half of the circumference of the computational domain was treated as a uniform velocity inlet while the rear half was considered as a pressure outlet. In the case of bounded flow, the cylinder was placed between two streamwise symmetrical flat plates (walls) with a uniform velocity inlet at 15d upstream and pressure outlet at 20 d downstream from the centre of the cylinder. A no-slip boundary condition was applied on the cylinder surface, on the top and bottom walls (in the case of bounded flow) of the computational domain.
