Mr Han Peng is a postgraduate research student within Engineering and Physical Sciences at the University of Southampton.

Han Peng studied for a Bachelors degree on aircraft power engineering in 2016, and a Master degree on aeronautical engineering in 2019 with a thesis entitled 'Study of the mechanism on flame propagation and deflagration to detonation transition with fluidic obstacles' at Xiamen University, China. Now, he is a PhD student at the University of Southampton, aided by the China Scholarship Council. His PhD topic is about the simulations of the supersonic combustion in rotating detonation engines.

Simulation of the supersonic combustion in rotating detonation engines

The RDE, which employs pressure-gain combustion, is able to operate with limited or no mechanical compression. The detonation wave rapidly propagates in the combustor resulting in a nearly constant-volume combustion process that produces high-pressure burnt products and provides the thrust. In order to reduce the computational cost, a 3-D annulus RDE can be unwrapped into a 2-D plane. The 2-D Navier-Stokes equations with detailed chemical kinetics are solved based on a Cartesian mesh in AMROC -Clawpack. A second-order accurate MUSCL-Hancock scheme with Minmod limiter is used for the reconstruction. A hybrid Roe-HLL Riemann solver is utilized to evaluate the inviscid fluxes. For multi-dimensional problems, the hybrid Roe-HLL solver is combined with the wave propagation method. The premixed hydrogen/air RDE and ethylene/oxygen RDE are tested with continuous and discrete injection, respectively.
