Areas of interest: 

Primary research theme: Aerodynamics and Fluid Mechanics
Research Labs and Groups: Fluid Dynamics Laboratory

Our research interests lie in the broad area of fluid dynamics, specializing in fundamental and applied aspects of turbulent flows. Of primary interest is how the initial/upstream conditions determine the life-cycle of large-scale coherent vortical structures and small-scale turbulent properties of the turbulence field. Understanding the life-cycle of large-scale coherent vortical structures are of paramount importance as they are responsible for, amongst other things, drag force, noise generation and the spread of pollution. In order to better understand the effects of initial conditions on these vortical structures, we use multiscale (fractal) geometries and an array of experimental techniques (e.g. time-resolved PIV, hot-wire anemometry and time-resolved force/torque measurements) to gain insights into the underlying physics. In tandem with the fundamental aspects, we also consider engineering applications of such designs, targeted at the aerospace and renewable energy.
