A Numerical Study on the Near Body Vorticity Dynamics of a Square Cylinder under Inline Pulsatile Flow

In this thesis, flows past objects of different shapes are predicted by computer simulation to analyse the way that swirling flow develops as the fluid passes and moves downstream. It turns out that object shape and whether it can vibrate are important factors determining the governing flow physics, and have a strong influence on the force experienced by an object. This analysis enables wake flow patterns to be better predicted and understood. This study is of potential interest to improving mixing devices and in the control of flow-induced vibration of engineering structures such as buildings, chimneys or oil rigs.
