Abstract
The variation of the steady force coefficients for a two-dimensional circular cylinder and a triangular prism due to wall interference is reported here for a large range of blockage ratios. The effect of wall constraint on the Strouhal frequency is also examined for a limited range of blockage ratios. A simple choice of the scales of velocity and lengths constituting the force coefficients and the Strouhal number for constrained flows is proposed to include blockage effects.
