Computations of a Bluff-Body Stabilised Premixed Flames Using ERN Method
ChemEngineering, 2022 Combustible carbon-based energy is still prevailing as the world’s leading energy due to its high energy density. However, the oxidation of these hydrocarbons disturbs the natural carbon cycle greatly by increasing greenhouse gases.

DNS for Turbulent Premixed Combustion
, 2021 Most of practical combustion occurs in turbulent flows which involve strong coupling between turbulence and chemical processes. The heat release from combustion alters the fluid properties such as density and viscosity and in turns affects the turbulence.

Imaging Diagnositics of Combustion Instability in Premixed Swirling Combustion
Proceedings of Global Power & Propulsion Society, 2019 An experimental study on combustion instability is presented with focus on propane-air premixed swirling flames. Swirling flames under self-excited oscillation are studied by imaging of visible light and OH* chemiluminescence filter under several typical conditions.

Heat release rate surrogate for ammonia–hydrogen premixed flames under various conditions
Applications in Energy and Combustion Science, 2023 Blending hydrogen has proven an efficient method to enhance the combustion stability of gaseous ammonia flames. Heat release rate (HRR), as an important parameter to indicate combustion process, is hard to be directly measured and highly dependent on the
