Research Activities

This research aims to fill a significant gap in the current modelling of critical fluid-structural interactions in high-speed flows by performing novel experiments to generate data that does not currently exist. This data is being used to assess and improve advanced numerical simulation tools. The effective development of high-speed vehicles and turbomachinery requires the accurate prediction of the behaviour and lifetime of structural components subject to these fluid-structural interactions in which the deformation of the structure, induced by the local flow field, can in turn influence…

In this seminar, I discuss the phenomenon of high frequency oscillations observed in the wake of a compressible wake, often observed behind reentry vehicles, reusable stages of rockets falling back to earth, etc.
Investigated turbulent fountains (e.g., volcanic eruptions, refueling systems) and negatively buoyant jets (discharge from desalination plants) over a large range of Reynolds and Froude numbers. The goal of this study was to develop new integral models for estimating the penetration depth and spreading rate of a negatively buoyant jets/ fountains.
I contributed to the design of this flow visualisation experiment carried out by Dr. J H Lee at University of Melbourne. In this experiment, we visualised the turbulent flow features (eddies, sweeping and ejection events) and physical phenomena (entrainment, broad range spectrum) in a fully turbulent flow.
This video explains the principle behind my PhD thesis project, i.e., manipulation of large-scale coherent structures in a turbulent boundary layer. The video was based on the research I carried out during my PhD using the large wind facility at The University of Melbourne, Australia.
