Propellant Mixing in Vortex Cooled Liquid Rocket Engines

Energy icon, disabled. An orange lightning bolt.

As temperatures in the combustion chamber of a liquid rocket engine during use can exceed 5,000 °F, a large portion of development is often focused on cooling. However, by injecting propellants tangential to the combustion chamber it is possible to create a vortex which separates hot combustion gases from the chamber wall. By studying this mechanism, cooling system complexity can be reduced while increasing engine efficiency.
