Numerical Investigation of Velocity and Pressure Fluctuations in the Wake of a Circular Cylinder Due To Transient Laminar Flow
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 4
Abstract
2D incompressible and transient flow around a circular cylinder has been carried out numerically by using CFD fluent. The wake is generated by a uniform laminar flow of Reynolds number (Re) 150 based on the characteristic length of the cylinder, D. Flow has been studied using the Navier-Stokes and Continuity equations as governing equations with FVM employing pressure based solver and PISO scheme. A computational grid independence study has been done to obtain a grid resolution which predicts the results without any discrepancies and to optimise the computational resource used. Flow parameters such as drag coefficient, Strouhal number, velocity contours, static pressure contours and vorticity contours are calculated in this work and are in good agreement with other numerical and experimental results.The pressure distribution in the near wake region and around the circular cylinder surface is also investigated which predicts the flow separation point. The results are presented in the form of coefficient of pressure Vs Domain length/D and Coefficient of pressure along the cylinder wall.
