Atomization Performance Study of a Fuel Injector in IGC by Experimental and Numerical Investigation
Fuel spray and atomization characteristics play an important role in the performance of internal combustion engines.Experimental and numerical atomization studies of the fuel injector used in IGC(Inner Guide-vane Combustor)under various assembly and operation conditions have been performed in order to determine the configurations of the fuel injector proposed for use in IGC.Droplet Sauter Mean Diameter(SMD)distributions were measured with Phase Doppler Analyzer(PDA)at different operating conditions and used to evaluate the atomization performance.Computational Fluid Dynamic(CFD)study has also been conducted based on Discrete Particle Model(DPM).Current work examines optimizing the atomizer location and assembly condition of these vanes and the cavity within them.Results reveal that the distribution of droplet SMD varies with the assembly and operation condition.The further results showed that fuel injector used in IGC with single slot,forward injection direction and <shaped backsplash type can get the best atomization performance compared with other cases tested.
