Flow Field Simulation between Angle Vane and Cylinder

Water flow around cylinder represents a noticeable problem in fluid mechanics. The computational fluid dynamic is employed to study numerically the turbulent flow field around a cylinder without vane and with vane respectively. The vane configuration and direction are considered in the numerical study. The analysis is done in two dimensions by using ANSYS software. The finite volume method is used to model and simulate the cases study. The numerical study concentrates on strain rate, stream function, swirling, vorticity, velocity in the flow direction, radial velocity, pressure distribution, pressure coefficient and drag coefficient. It is recognizing that the vane changes the flow field hydraulic response. It is found from the result that the vane more reduces the value of the drag coefficient as compared with the value of the drag coefficient when the cylinder is alone. The stream function reveal how much the fluid suffer from deformation while the strain rate reveal how much t5he flow velocity change with distance. Also, vorticity illustrate a dramatic hydraulic response especially in the case of the vane existence. The study shows that the vane has direct effect on the flow separation zone and dissipation the turbulent intensity before it passes the cylinder.
