The development of clean, sustainable energy systems is one of the grand challenges of our time. Despite the rise of renewable energy systems, most projections indicate that combustion-based systems will remain the predominant source for energy for the next decades. In order to satisfy high fuel efficiency and low emission, combustion systems are being driven closer to the bleeding edge of technology.
The talk has two parts. In the first part, a modelling of unsteady turbulent jet is presented. Direct numerical simulation (DNS) on a stopping jet is performed, and the temporal and spatial development of the unsteady jet is analysed. In the second part, the flamelet based combustion modelling (G-equation) is introduced and utilized to understand the turbulent Markstein length from the oscillating flame holder flame.
Dr Donghyuk Shin is a member of the Institute for Multiscale Thermofluids at the University of Edinburgh. He received his Bachelor’s degree from the Korea Advanced Institute of Science and Technology and his PhD degree from the Georgia Institute of Technology. After his PhD, he worked at Centre Européen de Recherche et de Formation Avancée en Calcul Scientifique (CERFACS), France and the University of Southampton as a postdoc. His research focuses on theoretical and numerical analysis on turbulent reacting flows.
