The three-dimensional effect of flow past bluff body poses difficult problems for simulation. The work here focuses on using high resolution TVD (total variation diminishing) numerical scheme to simulate the case of flow around a wall-mounted three-dimensional circular cylinder. The well validated TVD code for two-dimensional flow simulation is expanded to solve three-dimensional problems. This work gives a comparison between the results from the newly developed model and the results from previous numerical simulations as well as experiments. It is shown that present model poses reasonable results and predicts better velocity fields than previous model.
