Near-Field Mixing in a Coaxial Dual Swirled Injector. [PDF]
Flow Turbul CombustAbstract Improving mixing between two coaxial swirled jets is a subject of interest for the development of next generations of fuel injectors. This is particularly crucial for hydrogen injectors, where the separate introduction of fuel and oxidizer is preferred to mitigate the risk of flashback.
