Jack is undertaking his DPhil through the Centre for Doctoral Training in Gas Turbine Aerodynamics. He completed his Master of Research degree at the University of Cambridge as part of the same programme following undergraduate studies at the University of Warwick. His research focusses on particulate deposition in gas turbines, primarily bounce-stick behaviour. Predicting deposition and erosion is desirable both to quantify the cost of ownership effects that arise from atmospheric contaminants and to allow the optimisation of component design to minimise engine deterioration. Current work investigates how the solid mechanics of particle collisions influence the aerodynamics of particle rebound, in addition to the development of novel low-order methods that predict how a particle bounces in complex high-temperature conditions. Modelling particle trajectory, rebound and deposition also has applications in additive manufacturing, pipeline engineering and biomedical sciences – particularly concerning the respiratory system.
