- LinkedIn Profile
I graduated Mechanical Engineering at Aston University Birmingham in 2014. During the degree I have done a placement at Cummins Turbo Technologies where I was a rotor systems engineer for 14 months and supported research and development of bearing systems for the next generation automotive turbochargers. During the time in industry I have also carried out individual research work for improvement of the research techniques.
My main research interests are within fluid dynamics problems in engineering applications. I am particularly interested in heat transfer, aerodynamics research, power generation and mechatronics
PhD project outline
Future advanced military aircraft face an appreciable technical challenge to design thermal management systems of adequate capacity within installation constraints. Various heat exchangers (HE) constitute key components within aircraft thermal management systems and have a strong determining effect on overall system performance and feasibility. Novel manufacturing techniques (e.g. ALM) provide exciting opportunities for innovative HE geometry. This research will investigate and evaluate novel HE design for future aircraft thermal management and assess opportunities to improve thermal performance. Numerical thermofluids and CFD (such as OpenFOAM) modelling approaches will be used to develop validated models of existing and conceptual HE designs. The project will involve working alongside BAE Systems and a specialist HE supplier.
Why I chose the CDT in Fluid Dynamics
I chose CDT in Fluid Dynamics because of the importance of optimised fluid dynamics behaviour in many engineering applications. Additionally, the CDT is highly interdisciplinary which gives a unique chance to understand fluid dynamics from vast range of perspectives and has good links with world leading industry and academic institutions, enabling to build a professional network.
