Dataset for transient 3D simulations of turbulent premixed flames of Gas-to-Liquid (GTL) fuel

open access: yesData in Brief, 2021
A fan-stirred combustion vessel is used to study the premixed turbulent combustion of diesel, Gas to Liquids (GTL) and 50/50 diesel-GTL and to generate these datasets.

A Combustion Regime-Based Model for Large Eddy Simulation

open access: yesEnergies, 2021
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.

Combustion Regimes in Turbulent Non-Premixed Flames for Space Propulsion

open access: yesAerospace, 2023
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 Comparison between Statistical Behaviours of Scalar Dissipation Rate between Homogeneous MILD Combustion and Premixed Turbulent Flames

open access: yesEnergies, 2022
Three-dimensional Direct Numerical Simulations (DNS) data has been utilised to analyse statistical behaviours of the scalar dissipation rate (SDR) and its transport for homogeneous methane-air mixture turbulent Moderate or Intense Low oxygen Dilution ...

A Lagrangian-based flame index for the transported probability density function method

open access: yesTheoretical and Applied Mechanics Letters, 2022
We propose a new flame index for the transported probability density function (PDF) method. The flame index uses mixing flux projections of Lagrangian particles on mixture fraction and progress variable directions as the metrics to identify the ...

Numerical investigation of the premixed V-flame stabilization and blowout [PDF]

open access: yesمهندسی مکانیک شریف, 2021
Global warming and high fossil fuel consumption increase the application of the low-Nox burner with lean-premixed combustion. However, this type of combustion is more susceptible to thermoacoustic instabilities.

Karlovitz Numbers and Premixed Turbulent Combustion Regimes for Complex-Chemistry Flames

open access: yesEnergies, 2022
The structure of premixed turbulent flames and governing physical mechanisms of the influence of turbulence on premixed burning are often discussed by invoking combustion regime diagrams.

Modelling of Conditional Scalar Dissipation Rate in Turbulent Premixed Combustion

open access: yesComputation, 2021
In turbulent premixed flames, for the mixing at a molecular level of reactants and products on the flame surface, it is crucial to sustain the combustion.
