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

A New Analytic pdf for Simulations of Premixed Turbulent Combustion
Flow Turbulence and Combustion, 2020 A new reaction rate source term $$\omega _m(c)$$ ω m ( c ) for modelling of premixed combustion with a single progress variable c is proposed. $$\omega _m(c)$$ ω m ( c ) mimics closely the Arrhenius source term $$\omega _A(c)$$ ω A ( c ) for a large ...
