Summary

Abstract

Moderate or intense low-oxygen dilution (MILD) combustion, also known as flameless combustion, has drawn much attention as a unique phenomenon and a clean technology of combustion with super-low NOx emission. In the context of global warming and atmospheric pollution, MILD combustion is ideal for enhancing thermal efficiency and reducing emissions. In this seminar, some fundamental research on the occurrence and emission characteristics of MILD combustion will be introduced. In order to quantitatively explore the profiles of this combustion phenomenon, methods of chemical calculations, CFD simulations and laser diagnostics using absorption spectroscopy are developed and conducted. The principles of these methods and the latest work by Dr Cheong’s Group regarding these methods, particularly the advances in tomographic absorption spectroscopy, will be presented.

Speaker

Dr Kin-Pang Cheong is currently an Associate Professor in the School of Aeronautics and Astronautics at Sichuan University. He received his BSc and PhD degrees in Energy and Resources Engineering in 2011 and 2017, respectively, from the College of Engineering at Peking University. Afterwards he worked as a Postdoctoral Fellow with Prof. Wei Ren in the Department of Mechanical and Automation Engineering at The Chinese University of Hong Kong. Dr Cheong’s research interests include advanced combustion and propulsion technologies, fluid phenomena and laser diagnostics. He has received fundings from NSFC, Science & Technology Department of Sichuan Province and industrial companies. He was awarded Talents of Sichuan Province and Youth Scholar of Sichuan University in 2019 and 2021, respectively.
