This paper paves the way to geometry analysis of surpass component of the main structure using the vortex instabilities. From the literature review it is found out there is no study developed or arranged with the geometry influences. The influence of the fluid flow, main structure and the distance between surpass body and the main structure is involved in each study. So this paper may have new investigation results in the field of vortex analysis. The present paper also focuses on the analysis of two dimensional flow past a circular cylinder in a specific laminar and turbulent flow regimes. In this simulation, an implicit pressure-based finite volume method is used for time-accurate computation of incompressible flow using second order accurate convective flux discretization schemes. The computation results are validated against measurement data for coefficient of drag, coefficient of lift on the body due to vortex instabilities. The project also look upon how to reduce the vortex instabilities using surpass component.
