About the Project

Applications are invited for a research studentship in the field of Thermofluids leading to the award of the PhD degree. The focus will be on developing and understanding new operation concepts for high-efficiency green engines running on zero-carbon fuels like hydrogen and ammonia, using advanced experimental techniques.

Project Description 

This project will investigate the fundamentals of fluid dynamics, mixture formation and ignition in internal combustion engines running on hydrogen and ammonia fuels using advanced optical diagnostic experimental techniques. Key areas of study will include direct fuel injection and air mixing in a fully optical engine with flexible valvetrain and boosting systems, to investigate advanced ignition and combustion modes aiming for a zero-carbon zero-emission engine. The research methods will give a full picture of in-cylinder effects related to various engine operating regimes. 

The Thermofluids Division at Imperial has an internationally leading record in fundamental and applied research into multiphase and reacting flows, established over several decades. You will be an enthusiastic and self-motivated person who meets the Academic requirements for enrolment on the PhD degree at Imperial. You are expected to have a 1st or upper 2nd class honours degree in Mechanical Engineering or a related subject, and an enquiring and rigorous approach to research, together with a strong intellect and disciplined work habits. A keen interest in experimentation and future high-efficiency zero-carbon engine systems is important. Excellent observational, practical and communication skills are all essential for this post.
