Wall-quenching Model in a CFD Simulation of Engine Combustion

CFD Simulation of HSDI Engine Combustion Using VECTIS

As part of the VECTIS code validation programme, CFD simulations were conducted to investigate direct-inject (DI) diesel engine combustion with the newly implemented Ricardo Two-Zone Flamelet (RTZF) combustion model. A small HSDI research engine was chosen as subject. The simulation programme consisted of 6 cases forming a complete injection time swing. CFD simulation results were compared dire...

Improving Simulation Accuracy of a Downsized Turbocharged SI Engine by Developing a Predictive Combustion Model in 1D Simulation Software

In this paper we aim to develop a predictive combustion model for a turbocharged engine in GT-Power software to better simulate engine characteristics and study its behavior under variety of conditions. Experimental data from combustion was initially being used for modelling combustion in software and these data were used for model calibration and result validation. EF7-TC engine was chosen for...

CFD Simulation of Catalytic Combustion of Benzene

A Mixture Fraction Combustion Model for Fire Simulation Using Cfd

Numerical Simulation of Combustion with Porous Medium in I.C. Engine

Porous media has interesting features in compared with free flame combustion due to the extended of the lean flammability limits and lower emissions. Advanced new generation of internal combustion (IC) engines are expected to have far better emissions levels both gaseous and particulate matter, at the same time having far lower fuel consumption on a wide range of operating condition. These c...
