Abstract: In this project work an attempt is made to predict the far-field aero acoustics noise and aerodynamic drag coefficient for square and circles in the by using the instable Reynolds be close to Navier Stokes equation coupled with the Fowes Williames and Hawkings acoustics analogy. The consider square and circle cylinder have a diameter of 0.016 m and air flow over the cylinder has a Reynolds number of 54800.To reduce thee computational cost the simulation are conducted in a two dimensional computational domain. The obtained numerical results such as aerodynamic lift and drag coefficients and the aero acoustics properties are also compact with experiments. Attempts are also made to study the effect of cross section shape of cylinder an attack as well.
