Investigation of differential diffusion in lean, premixed, hydrogen-enriched swirl flames
Applications in Energy and Combustion ScienceHydrogen combustion is a promising alternative to fossil fuel combustion in an effort to reduce our carbon footprint. However, hydrogen combustion is prone to thermodiffusive instabilities largely dependent on differential diffusion, a phenomenon that ...

Gas Explosion Venting: External Explosion Turbulent Flame Speeds that Control the Overpressure
Chemical Engineering Transactions, 2016 In most vented explosions the peak overpressure is controlled by turbulent flame propagation external to the vent. This has been known for many years, but a method to predict the overpressure from the external flame speed has not been developed.

Turbulent flame speed of thermodiffusively unstable flames: experimental investigation and scaling
, 2023 This work presents an experimental set of Bunsen flames characterized by a moderate Reynolds number and a variable turbulence intensity. Ten lean hydrogen-enriched methane-air mixtures at three levels of turbulence are investigated, ranging from pure methane-air to pure hydrogen-air.

Anchoring of premixed jet flames in vitiated crossflow with pulsed nanosecond spark discharge
Applications in Energy and Combustion Science, 2020 This paper deals with the effect of non-equilibrium plasma on the anchoring of a premixed jet flame in hot vitiated crossflow at atmospheric pressure. The turbulent vitiated crossflow was generated by an array of 4×4 premixed turbulent jet flames burning

Reaction rates in premixed turbulent flames and their relevance to the turbulent burning speed
Symposium (International) on Combustion, 1989 An experimental procedure to measure the local reaction rate, in premixed turbulent flames is presented. It utilizes the flame crossing frequency sub-model for the reaction rate formulated by Bray-Champion-Libby (BCL) for turbulent flames with unstrained or equally strained flamelets. The experiments involve measuring the flame crossing frequencies and
