Combustion Regimes in Turbulent Non-Premixed Flames for Space Propulsion
Direct numerical simulations of non-premixed fuel-rich methane–oxygen flames at 20 bar are conducted to investigate the turbulent mixing burning of gaseous propellants in rocket engines. The reacting flow is simulated by using an EBI-DNS solver within an

A Generalised Series Model for the LES of Premixed and Non-Premixed Turbulent Combustion
In this study, the generality and prediction accuracy of a generalised series model for the large eddy simulation of premixed and non-premixed turbulent combustion is explored. The model is based on the Taylor series expansion of the chemical source term

Non-Premixed Filtered Tabulated Chemistry: Filtered Flame Modeling of Diffusion Flames
The flame front filtering is a well-known strategy in turbulent premixed combustion. An extension of this approach for the non-premixed combustion context has been proposed by means of directly filtering counterflow diffusion flamelets. Promising results

Effects of hydrogen addition on NOx formation in a non-premixed methane low-NOx combustor
Hydrogen is a promising carbon-free fuel, but nitric oxides (NOx) emissions are significantly increased with higher temperature in hydrogen combustion.

Computations of a Bluff-Body Stabilised Premixed Flames Using ERN Method
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.

A Combustion Regime-Based Model for Large Eddy Simulation
The aim of this work is to propose a unified (generalized) closure of the chemical source term in the context of Large Eddy Simulation able to cover all the regimes of turbulent premixed combustion.
