Abstract:

In the present study, the objective is to analyse the flow physics in flow past cylinders for sub critical flow regime. The software used is Fluent 17.1. It is found that pressure decreases and turbulent kinetic energy increases suddenly at the downstream of the flow behind the cylinder. Flow separation and wake effect can be clearly visualised. Also, Fast Fourier Transform (FFT) is done using MATLAB software which indicates the presence of multiple frequencies in drag and lift forces.
