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...

description Swirling fluid motion in enclosed chambers was studied using two methods, simulations using computational fluid dynamics, and experimentation using particle image velocimetry.
