Abstract - Computational fluid dynamics (CFD) approach can reduce the expenses as well as time to provide an insight into the characteristics of flow and combustion process inside the combustion chamber at design stage. Geometry of the aero engine combustor simulated for investigation is an 18° sector of an annular combustor. Primary secondary and dilution holes are simulated on the inner and outer liner walls. Swirlers are provided on the thrust chamber to give uniform rotational velocity distribution as well as a thicker and higher velocity reverse flow core. Temperature has been analyzed in the annulus region. Liner holes provided on the surface of the chamber allows an air lining to form around the inner surface of the combustor, thereby maintaining the inner temperature of the combustor by reducing the heat flow towards the outer casing. So the location and orientation of the liner holes are selected on the basis of minimal heat loss to the surroundings and heating of the outer casing so that the material selection for the casing and related areas become less complicated and can reduce the application of various wall cooling methods. Nano fuel particle injection is employed to ensure thorough mixing and complete combustion of fuel there by reducing the pollutant emissions.
