For a series of single unlike-doublet elements, cold flow, mixing tests were performed to (1) establish the validity of the correlating parameters as indicators of mixing efficiency, and (2) to represent the mixing characteristics of particular N2O4/Amine injector designes. Specific selections and sizing of injector element types were based on a hot-fire injector performance evaluation program. The objective of this program was to develop an understanding of the criterias that cause reactive stream separation (RSS), commonly called “blowapart”, for N2O4/Amine propellants. This paper describes an analytical model defining the relationship between combustion performance and the propellant spray mixing quality determined by cold-flow measurements. Experimental verification of the results predicted from cold-flow analysis is also described. Comparisons of the effect of mixing uniformity on the C* mixing limited performance for N2O4/MMH combinations are then made. Following Rupe we confirm that Rupe’s mixing uniformity criteria is equal to 0.5 for Optimum mixing. For non-reactive stream separation, a simple relationship between mixing uniformity and mixing limited C* efficiency can be used to predict actual C* mixing limited performance.
