Simulation of Turbulent Combustion Using Various Turbulent Combustion Models

2009 Asia-Pacific Power and Energy Engineering Conference, 2009
The reynolds-averaged navier-stokes (RANS) method nowadays still is the major tool for gas turbine chamber (GTC) designers, but there is not a universal method in RANS GTC spray combustion simulation at present especially for the two- phase turbulent combustion.

Fractal modelling of turbulent combustion

Combustion Theory and Modelling, 2000
In a previous paper we proposed a new model for turbulent flows, called the fractal model (FM), which is applicable both to RANS and LES formulations. Here, the model is extended to the reactive case with the goal of simulating turbulent flames, both premixed and non-premixed.

Turbulent Combustion

1993
Abstract In most practical combustion devices the flow is turbulent. Therefore there has always been strong applied interest in turbulent combustion. Thus far we have studiously avoided mentioning turbulence, except where absolutely necessary, because of the complications that it introduces. Important combustion principles can be defined

Turbulent combustion of alcohols

Combustion, Explosion and Shock Waves, 1986
The authors experimentally and mathematically investigate the turbulent combustion of methanol and ethanol fuels and their mixtures with methane and ethane in order to comparatively assess the feasibility of these fuels for substitution in automobile engines from the standpoint of increased fuel economy and decreased nitrogen oxide emissions.

TURBULENCE AND TURBULENT COMBUSTION IN SPARK-IGNITION ENGINES

Progress in Energy and Combustion Science, 1976
Publisher Summary The turbulent flow field in an engine plays an important role in determining its combustion characteristics and thermal efficiency. The details of the turbulence structure in the engine are needed for determining heat transfer rates, ignition delay times, minimum ignition energy, and the rate of mixing and burn-up of quench layers ...

Control of Turbulence in Combustion

1989
Passive shear-flow control methods are being investigated to enhance turbulence for subsonic combustion. In this paper, two control methods are discussed. These methods were developed in subsonic nonreactlng flows and verified in subsonic combustion processes to avoid combustion Instabilities in a dump combustor.

Combustion Physics: Turbulent combustion modelling

Physics Bulletin, 1984
Turbulent combustion modelling as a major distinctive topic has been with us now for more than ten years. Increasingly it has attracted the interest of fluid dynamicists and applied mathematicians, groups without established interests in chemically reacting flows.

Aspects of turbulent combustion

15th Aerospace Sciences Meeting, 1977
A complete second-order closure program for the investigation of chemically reacting turbulent flowfields is being developed. Many of the turbulence models being used have been developed and tested during previous studies of a variety of incompressible and compressible shear flows.

In-cylinder motion and turbulent combustion

1999
The induction of air or an air/fuel mixture into the engine cylinder leads to a complex fluid motion. There can be an ordered air motion such as swirl, but always present is turbulence. The bulk air motion which approximates to a forced vortex about the cylinder axis is known as axial swirl, and it is normally associated with direct injection diesel ...
