Large Eddy Simulation of a Swirl-Stabilized Pilot Combustor from Conventional to Flameless Mode

Journal of Combustion, 2016
This paper investigates flame and flow structure of a swirl-stabilized pilot combustor in conventional, high temperature, and flameless modes by means of a partially stirred reactor combustion model to provide a better insight into designing lean ...

Multiscale combustion and turbulence

Proceedings of the Combustion Institute, 2009
AbstractMultiscale physics is the interaction of different physical processes occurring at largely separated scales. In combustion, many elementary reactions combine to only a few, but still have separated time scales. In flames, owing to the presence of diffusion, time scales manifest themselves as length scales, i.e.

An Experimental Study on the Effects of Pre-Chamber Geometry on the Combustion Characteristics of Ammonia/Air Mixtures Using Turbulent Jet-Post Spark Ignition Strategy

Energies
As a carbon-free fuel, ammonia faces challenges in engine applications due to its low flame propagation speed and high ignition energy. The pre-chamber turbulent jet-post spark ignition strategy (TJ-PSI) has been proven effective in accelerating the ...

Combustion Characteristics of Liquid Ammonia Direct Injection Under High-Pressure Conditions Using DNS

Energies
As a zero-carbon fuel, ammonia can be directly employed in its liquid form. However, its unique physical and chemical properties pose challenges to its application in engines. The direct injection of liquid ammonia is considered a promising technique for

Development and Validation of a Compressible Reacting Gas-Dynamic Flow Solver for Supersonic Combustion

Dynamics
An approach based on the OpenFOAM library has been developed to solve a high-speed, multicomponent mixture of a reacting, compressible flow. This work presents comprehensive validation of the newly developed solver, called compressibleCentralReactingFoam,

RESEARCH OF THE COMBUSTION PROCESS OF LIQUID FUELS AT THE CHANGE OF THE INJECTED PARTICLE’S VELOCITY

Вестник. Серия физическая, 2008
The combustion process of liquid fuel in the combustion chamber on the basis of the solution for differential two-dimensional equations of the turbulent reactive flows has been numerically researched. The influence of the spray velocity on the combustion
