Abstract: 
Direct numerical simulation of the wake flow around and behind a planar ellipse using a random vortex method is presented. Fluid is considered incompressible and the aspect ratios of ellipse and the angles of attacks are varied. This geometry can be a logical prelude to the more complex geometries, but less time dependent experimental measurements are available to validate the numerical results. Therefore, the key figures of the averaged values of selected cases are chosen to check the accuracy of the results. Based on the results, the general behavior of the flow around an ellipse at the zero angle of attack is almost similar to that around a circle. But, at the other angle of attacks, the asymmetry of the flow is dominant and pronounced clearly.
