Abstract:

The relation developed by Rizk and Lefebvre in 1985 and modified by Suyari and Lefebvre in 1986 and Wimmer and Brenn in 2013 is the primary relation used to predict the performance of simplex swirl atomizers, but these have never been tested for the conditions involved in hybrid rocketry. After developing a baseline expectation for accuracy of the relation with standard case atomizer experimental data, the relation was then compared to standard geometry cryogenic fluid experimental cases and computational cases of large geometry atomizers. While the relation shows good agreement with the cryogenic case with similar pressure and geometry, it is more inaccurate by an order of magnitude in cases with the larger geometry commonly used in hybrid rocketry.
