Abstract
The liquid–liquid bipropellant pressure swirl atomizers have been widely used in rocket engines to take advantage of their high mixing efficiency within the short length of the combustion chamber In this kind of engine the uniform mass distribution and propellant mixture ratio have great influence on combustion efficiency and instability The present work investigates the effect of the number of tangential passages on the spray cone angle mass distribution and propellant mixture ratio of a bipropellant atomizer Thus three atomizers were designed manufactured and evaluated experimentally The results showed that the number of tangential passages has some influence on the circumferential mass distribution however spray angle and propellant mixture ratio have not presented significant variations
