Mixing Characteristics of Kerosene-Lox in a Swirl Injector at 100 bar

Mixing Characteristics of Kerosene-Lox in a Swirl Injector at 100 bar

The The turbulent mixing characteristics of Kerosene-LOx in a coaxial swirl injector 100 bar have been numerically investigated. Turbulent model is based on large eddy simulation with real-fluid transport and thermodynamics. The effects of equation of state (EOS), chamber pressure are evaluated in a point of the mixing efficiency and pressure fluctuations. The dominant frequency is same as the hairpin vortex shedding frequency generated by film wave at the LOx post.
