book large eddy simulation (LES) technique are becoming a common reality in many branches of engineering and science, its application to engine flows has lagged behind due to the relatively more complex nature of both the flow and the geometry relevant to in-cylinder by: Combustor Stringent emissions standards imposed in recent years have led to the design and installation of lean, premixed gas turbine combustors.

In these type of combustors structural failure may take place because of thermoacoustic combustion instabilities which occur at various operat-ing ranges including lean conditions. A survey is also made of the potentials of multidimensional calculation in predicting performance and emission characteristics.

Lastly recent trends of performance relevant to combustion and emissions as well as combustion with alternative fuels are described by: Significant works and improvements have been made to model combustion in GDI engines using various models based on different approaches for treating the flame propagation.

Contrariwise, modelling studies on emissions from GDI engines are relatively scarce as compared to those performed on diesel engine combustion by:   Behrendt T, Carl M, Heinze J, Hassa C, Optical measurements of the reacting two-phase flow in a realistic gas turbine combustor at elevated pressures.
