Abstract

The objective is to analyse the flow physics in flow past cylinders for sub critical flow regime in the present study. The software used is Fluent 17.1. It is found that pressure decreases, and turbulent kinetic energy suddenly increases the cylinder's flow downstream. Flow separation and wake effects can be visualized. The Fast Fourier Transform (FFT) is also done using MATLAB software, which indicates multiple frequencies in drag and lifts forces.

Keywords

FFT, Flow separation, turbulent kinetic energy, sub critical
