Influence Of Fuel Injection Techniques On Combustion Performance Of Multi-Jet Shear Layer Combustion

Experimental work was carried out to study the effect of fuel injection techniques on the high intensity non-swirl multi-jet shear layer combustion performance of a fourhole conical burner. Two modes of gas oil fuel injection were investigated using a simple type atomiser with four holes positioned...

description Experimental work was carried out to study the effect of fuel injection techniques on the high intensity non-swirl multi-jet shear layer combustion performance of a fourhole conical burner.
