The development of asymmetric wake behind an aerofoil in turbulent incompressible flow has been computed using finite volume scheme for solving two‐dimensional Navier‐Stokes equations along with the k‐ε model of turbulence. The results are compared with available experimental data. It is observed that the computed shift of the point of minimum velocity with distance is sensitive to the prescribed value of the normal component of velocity at the trailing edge of the aerofoil. Making the model constant Cu as a function of streamline curvature and changing the production term in the equation for ε, has only marginal influence on the results.
