Flow and combustion problems are central to many energy systems, which often affect the efficiency of the system and emission of pollutants. An in-depth understanding of the flow and combustion problems is essential to their effective control.
Besides experimental studies, advanced numerical simulations and modelling can provide physical insight into the problems. In many cases, direct numerical simulation (DNS) can provide results that are not possible by using any other means, while large-eddy simulation (LES) is being adopted by industry as a more practical tool.
In this presentation, the applications of DNS and LES to challenging multi-phase, multi-scale and multi-physics problems will be discussed, including fuel injection and spray combustion in combustion engines. The presentation will then focus on some important research topics related to future energy systems such as the study of carbon capture and storage (CCS) using multiscale modelling.
