I am passionate about using computers to model the world around us. Simulating the properties of gases sparked my interest so I took it on as a personal project. After reading the literature about molecular dynamics, I decided to start (relatively!) simple and model a monoatomic gas such as argon.
I wrote a program in python which worked as follows:
I used the time-averaged data generated from each simulation to explore the macroscopic properties of argon. Plotting the particle velocities yielded a Maxwell-Boltzmann distribution (above) which indicated the simulation was working as expected.
Furthermore, I used metrics such as the mean-squared-displacement to calculate the phase of the ensemble given the positions as a function of time. This allowed me to produce a temperature-pressure phase diagram (above right) which predicted the melting and boiling point of Argon to within 15% error.
In addition to modelling gases, I have enjoyed modelling fluids computationally as well. As part of an extended fluids project I undertook at school, I wanted to teach myself fluid dynamics and explore the vast field of Computational Fluid Dynamics.
I learnt how to solve the Navier Stokes equations numerically (and analytically in some cases) for simple laminar flow through a 2D pipe. I then extended the solver to 3D and compared the calculated velocities to the analytical solution (above).
Once I had analysed these simple cases, I felt prepared to move onto more complex flows. I modelled the flow around a rectangular object in an infinite 2D plane, assuming there is no turbulence (see left). By analysing the velocities at the boundaries I could calculate the total force on the obstacle using the steady flow momentum equation. Varying the angle of attack of the 'wing' enabled me to produce a simplistic graph of lift-to-drag ratio and calculate the optimum angle of attack.
Cascade is a Cambridge University society which aims to create a data-driven sustainability app. The goal is to help individuals control their climate impact and use that momentum to make change among communities, governments and industries.
I lead the coding team which currently has about 20 members and I am also part of the product management team. I am responsible for:
As of writing, we have created a website with landing pages for users to get more information about the project and sign up to be a beta tester.
HappyrHealth is a startup that is building an app to help track and manage migraines for children. I have worked with them since June 2020 to create a web-based prototype for their app.
I have been responsible for discussing the technical side of the project with the founders and for coding the webapp. The features I have implemented are:
Initial testing has received promising feedback and the prototype has been important in directing the project roadmap.
Since joining the university, I have been an active member of the Cambridge University Eco Racing Society. As part of the electrical team, I am implementing a telemetry system to monitor the internal state of the car. I enjoy the challenge of integrating with the different electrical interfaces and I currently have a system with the following components:
Unfortunately we have not been able to access the car recently due to Coronavirus so the system can only be tested on simulated data.
Full Blue Racing is a society that builds a petrol racing car to compete in the annual Formula Student competition. I joined the society this year but unforunately we haven't been able to work on the car due to the current circumstances.
Nevertheless, I have been worked remotely to create an internal management system (see above) for the society (which has in excess of 50 members). Currently the features include:
