| Summary: | A study on the effect of allocating a square blockage in front of a rotating cylinder is presented. The aim of the study is to determine the optimum design of the blockage to enhance the lift generating performance of the rotating cylinder. A numerical simulation is carried out to investigate the effect of different sizes of blockage towards the lift generating performance of the rotating cylinder. The simulation adopted a fully turbulent flow, having Reynolds number of 600and the spinning of the cylinder at 100 RPM. The validation of simulation results from RANS code FLUENT is done through comparison with the published results from past studies. In general, the results suggest that lift generating performance of the rotating cylinder will be improved by placing a blockage in front of it |
