Abstract

Plows in the LOX manifold with two different types of predistributor have been analyzed using a CAE technique. The computational geometry and flow condition through the injection holes resemble those in the actual manifold of the liquid rocket, so that the results can describe the actual flow reasonably It is noted that two different types of predistributors lead to very similar pressure and mass distributions in the plane just above the injection holes. Also the pressure drop across the injection holes is rather uniform regardless of location of the holes and this would suggest that the simplified modeling of the flow through the injection holes is possible from an engineering point of view.
