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...

Numerical Flow Simulation of a Natural Gas Engine Equipped with an Unscavanged Auto-Ignition Prechamber

A three-dimensional Reynolds-Averaged Navier-Stokes (RANS) simulation was carried out on an unscavanged auto-ignition prechamber-cylinder configuration in order to understand better the ignition conditions inside the engine. The sensitivity to different boundary conditions like initial gas and wall temperature was tested and flow simulations coupled with a 55 species chemical mechanism were car...

Numerical Simulation of Cryogenic Injection in Rocket Engine Combustion Chambers

The numerical simulation of cryogenic combustion is crucial for a better understanding of the complex physics involved in reactive flows of rocket engines and to help to reduce the development cost of these engines. The focus of this study is set on the oxidizer injection and its dispersion through jet dense core destabilization and atomization or supercritical mixing. Specific models have been...
