Research interests
The development of advanced gas turbines for use with non-conventional energy vectors like hydrogen is of much interest due to the push towards decarbonisation in the power and propulsion sectors. However, the lean hydrogen flame is known to be highly unstable and can result in the occurrence of flame extinction, which may lead to flame blow-off. This is detrimental to combustion systems and must be avoided.
Computational Fluid Dynamics (CFD) is widely used for turbulent combustion modelling and is relied on for the design of industrial combustors today. Large Eddy Simulation (LES) is a powerful emerging methodology for CFD due to its capability of handling full-scale complex geometries and the ability to capture the unsteady phenomena in turbulent combustion, including flame stabilisation and blow-off in industrial gas turbines. The use of flamelet-based models for capturing the interaction of turbulence and combustion are used to reduce the computational cost for LES and are widely used in CFD codes today.
Biography
Caleb J Li is a PhD student working under the supervision of Prof Swaminathan in the energy group of Division A and funded by Mitsubishi Heavy Industries (MHI). The research is focused on developing models to improve predictions of hydrogen flame stabilisation and blow-off using large eddy simulations and implementing those into OpenFOAM.
