Research

I'm currently a PhD student at University of Southampton studying cavitation collapse in complex geometries. I graduated from University of Southampton in 2019 with an MEng in Aeronautics and Astronautics with a focus on Computational Engineering and Design. Below are my current and past research projects. You can also find me on various platforms using the links below, or email me at [email protected]

Bubble Collapse Near Porous Plates

The collapse of a gas or vapour bubble near a solid boundary produces a jet directed towards the boundary. A porous boundary, such as a filter, would act similarly to a solid boundary but with reduced effect. We experimentally investigate how a porous plate affects bubble collapse.

Modelling Bubble Collapse Anisotropy

A gas or vapour bubble collapsing in the vicinity of a rigid boundary displaces towards the boundary. The displacement has been shown to be a function of the 'anisotropy' of the collapse, measured by a dimensionless representation of the Kelvin impulse known as the anisotropy parameter. We develop an inexpensive Boundary Element Method model capable of predicting the anisotropy parameter for any rigid complex geometry.

Cavity Collapse Near Slot Geometries

Vapour bubbles in water collapse towards a nearby solid boundary producing a jet that can clean, or damage, the boundary. It is useful to understand how different boundary geometries will affect the direction in which the jet is produced. We numerically and experimentally investigate how a slot in a flat boundary affects the jet direction of a single bubble.

GPU Enabled Particle Simulation

My undergraduate individual project centered around implementing the Discrete Element Method for a GPU using OpenCL. The program was used to simulate and analyse agglomeration behaviour in a series of Taylor-Green vortices.
