## Abstract

The project report deals with the analysis of the fluid flow phenomena at different conditions, utilising the CFD simulation software ANSYS. Starting off with the work, a tank of sides 10m is considered. The tank is provided with a cylinder at the centre, with a diameter of 1m. Certain fluid is made to flow through the cylinder, thus rotating the cylinder with the angular velocity ranging from 0rpm to 100rpm. The Reynolds Number is taken into account and is varied from single-digit value 1 to multi-digit value 10,000. On each Reynolds Number value being considered, the cylinder is rotated at different angular velocities ranging from 0rpm to 100rpm. On each of these values, the simulation is done using ANSYS 13.0. Workbench is used for the geometry purpose while Fluent 6.2.16 is utilised for the rest of the simulation purpose. The value of drag coefficient is obtained at all these combinations of Reynolds Number and angular velocity. The tabulation is done and the hence the pattern is observed. Hence a common conclusion is drawn from all the tabulations done. This gives the idea regarding the relationship between angular velocity, Reynolds Number and drag coefficient.
