Numerical simulations of gaseous flames in combustion chamber applications

Large Eddy Simulations of gaseous flames in gas turbine combustion chambers

Recent developments in numerical schemes, turbulent combustion models and the regular increase of computing power allow Large Eddy Simulation (LES) to be applied to real industrial burners. In this paper, two types of LES in complex geometry combustors and of specific interest for aeronautical gas turbine burners are reviewed: (1) laboratory-scale combustors, without compressor or turbine, in w...

Numerical simulations of reverberation chamber

The focus of this project is to determine whether commercial general purpose raybased electromagnetic analysis tool (XGYD by Remcom, Inc.) can be an effective and accurate method of simulating a reverberation chamber and wireless communication within a confined and reflective environment, like a car. An introduction that includes the mathematical equations which govern the wireless channel is g...

In-Chamber Analysis of Pollutants Formation in Diesel Combustion by Spectral Measurements and Numerical Simulations

Experimental difficulties in following the soot formation and oxidation processes in the environment of diesel engines are recognised in the high values of the in-chamber temperature and pressure and the presence of extremely reactive intermediate species. At present, optical techniques have overwhelmed lacks typical of both local in-cylinder and totalcylinder samplings, which allow a high temp...

Terascale direct numerical simulations of turbulent combustion using S3D

Computational science is paramount to the understanding of underlying processes in internal combustion engines of the future that will utilize non-petroleum-based alternative fuels, including carbon-neutral biofuels, and burn in new combustion regimes that will attain high efficiency while minimizing emissions of particulates and nitrogen oxides. Next-generation engines will likely operate at h...
