Timothy O’Sullivan is a third year Science student at The University of Melbourne. He is currently completing a Major in Physics and a Diploma in Applied Mathematics.
He will be pursuing a Master of Science degree, specialising in Applied Mathematics with a research focus in fluid mechanics. The intended research of his summer project will be on the Couette flow of a monoatomic fluid for which an analytical solution exists. Code will then be written in MatLab to test these analytical solutions and to test the limitations of the model. The results of this research may have implications for the design of nano-channel walls and in delaying the transition to turbulence.
Timothy has always been interested in the mechanisms of the natural world and his studies in Science and Mathematics allowed him to delve deeper into these curiosities. Particle physics is his current broad area of interest in physics, encompassing the topics of quantum physics, electrodynamics and special relativity. In terms of Mathematics, he is currently most interested in studies surrounding dynamical systems utilising ordinary and partial differential equations (which then inspired an interest in fluid mechanics) and complex analysis.
Aside from academia, he has also spent a lot of time involved in various sports including Basketball, Football (Aussie rules, still currently playing), Athletics and Swimming. Timothy is also an avid listener and producer of electronic music. His current favourite pass time is fishing various freshwater rivers around Victoria.
Fluid dynamics and molecular dynamics (MD) are increasingly used tools for micro and nano-electro-mechanical systems and biosensors. This project investigates a regime of a system consisting of a fluid confined between two solid walls moving relative to each other using macroscopic (FD) and microscopic (MD) simulations. The project will focus on a Couette flow of a monoatomic fluid for which an analytic solution exists. An MD code with Couette flow implementation and all pre and post-processing tools will be written and run in Matlab. Results will be compared to analytical solutions , and limiting regimes for continuum flow will be discussed.
