Numerical Simulation of Flow past a Circular Cylinder with Varying Tunnel Height to Cylinder Diameter at Re 40.

By Rajani B. N, R. V. P Gowda, P. Ranjan and Karnataka India


The current study mainly focuses on the two-dimensional numerical simulation of the unsteady laminar flow past a circular cylinder in a channel, mimicking the effect of the tunnel wall. The computational results obtained using two different flow solution codes are validated against other computational and measurement data available in the literature. The study confirms a decrease in wake length and a shift in flow separation further downstream at smaller gaps between the tunnel walls and cylinder
