Abstract

The authors have been developing fuel regression formulas for CAMUI type hybrid rocket motors. A fuel block in a CAMUI-type fuel grain is a short-axis cylinder having two axial ports. Previous experiments showed that an experimental constant in the regression formula for forward-end faces depends on port length L, mean port diameter D, and the Reynolds number of the flow. In this paper, the authors examined these effects more closely to clarify the basic mechanism of these dependencies.
