Swirl flow in combustion chambers
Swirling fluid motion in enclosed chambers was studied using two methods, simulations using computational fluid dynamics, and experimentation using particle image velocimetry. Using the tangential inlet configuration as the basic design, several different swirl generator models were created using co...
