Combustion Modeling in Internal Combustion Engines

Combustion Science and Technology, 1976
The fundamental assumptions of the Blizard and Keck combustion model for internal combustion engines are examined and a generalization of that model is derived. The most significant feature of the model is that it permits the occurrence of unburned hydrocarbons in the thermodynamic-kinetic modeling of exhaust gases.

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.

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.

A Model for Combustion of Fuel in the Boiler

1985
In the work theoretical model for combustion of fuel in the boiler is given. The model is nonlinear with variable time delay and is suitable for the cases with too much air and also covers some aspects concerning air deficit. The inputs of the model are norm fuel flow and norm air flow.

Modeling of Combustion Processes in Internal Combustion Engines

Chemistry and Technology of Fuels and Oils, 2000
Improving internal combustion engines (ICE) and increasing the quality of operation are linked with the necessity of maximally increasing the degree of compression. For ICE with spark ignition (otto cycle), the possibilities for such an increase are limited by “knock,” a complex, incompletely investigated phenomenon.

Comparison of droplet combustion models in spray combustion

27th Joint Propulsion Conference, 1991
This study compares the spray combustion characteristics predicted by the above three models with experimental observations resulting from various inlet mean droplet sizes. A simplified combustor, similar to that used for the spray BurkeSchumann diffusion flame, is assumed.

Modelling of Combustion In a Gas Turbine Combustion System

SAE Technical Paper Series, 2001
<div class="htmlview paragraph">The main aim of this work is to carry out a 3D flow field analysis of an annular gas turbine combustor using finite volume method. The numerical calculations are performed using Semi Implicit Method for Pressure Linked Equations (SIMPLE) algorithm with unstructured grid arrangement. The turbulence models tried are &

A Qualitative Model for Dynamic Combustion

SIAM Journal on Applied Mathematics, 1981
A qualitative model for studying shock-wave chemistry interactions in combustion theory is introduced. The model which we study bears the analogous relationship to reacting gas flow as Burgers’ equation does to ordinary compressible fluid flow. When the corresponding physical assumptions of the Chapman–Jouget and von Neumann–Zeldovich–Doring theories ...

MODELLING PULVERISED COAL COMBUSTION USING A DETAILED COAL COMBUSTION MODEL

Combustion Science and Technology, 2006
ABSTRACT The ability to assess the combustion behaviour of internationally traded coals and accurately predict flame characteristics, stable species concentration, unburned carbon and pollutant emissions is of importance to the power generating industry. Despite recent advances in coal combustion modelling detailed understanding is still lacking on the
