IMGP1082_2Welcome. If you have found your way to this site with little or no idea of who I am, then let me give you a brief and somewhat biased overview.

Currently, an Australian Research Council (ARC) Discovery Early Career Research Award (DECRA) Fellow and Lecturer (Advanced Aerodynamics and Thermodynamics), based at the Laboratory for Turbulence Research in Aerospace and Combustion (LTRAC) at Monash University in Australia, I completed a PhD in Mechanical and Aerospace Engineering under a joint degree (Cotutelle) program between École Centrale de Lille in the North of France and Monash University in Melbourne, Australia. My thesis focused on the development of an experimental technique for the three-dimensional measurement of complex fluid flows and fluid turbulence, using principles of tomography, holography and particle image velocimetry (PIV). Essentially this involves the use of high energy (400 mJ) and in some cases high speed (1.5 kHz) lasers to illuminate small glass spheres, smoke or liquid particles in wind and waters tunnel, with a short effective exposure time (9 ns). High resolution and high sensitivity digital cameras are used to record two images of the particles in the flow, with a short delay (~ ms) in order to enable the use of statistical cross-correlation techniques to determine the movement and velocity of these particles. If chosen correctly, these particles will faithfully follow the flow in the tunnel and hence enable the measurement of the instantaneous flow velocity in wind tunnels, jets and over aircraft, submarines, cars, wind turbines, etc. These techniques are extended to multiple dimensions using principle of stereo vision, such as that used in ‘3D movies’, or computerised tomography, like that used in a medical CAT scan. Both approaches require various elements of computer vision, medical imaging and image preprocessing.

At present my work is focused on experimental measurements and numerical simulations of complex multi-dimensional canonical turbulent flows and turbulent convective heat transfer. This includes applied flows over aircraft, submarines and torpedoes. This involves the design and setup of experiments, facilities, as well as the development of novel experimental measurement techniques and creation of various computer programs for the simulation of fluid flows and the processing and analysis of data. I hope some of my posts will give some insight into various aspect of this work as well as demonstrating tool and techniques that may have uses beyond the fields of Thermo-Fluids and Mechanical and Aerospace Engineering.
