The injection boundary conditions for the motor are defined by the velocity-temperature temporal correlations. Three different propellant morphologies are modeled and tested along with a random white noise model that represents the current surrogate for propellant modeling. The data gained from each of these simulations is compared using contour plots of the chamber flow characteristics and by performing FFT analysis on the head-end pressure histories. The study is then expanded to include analysis of the 70 pound version of the BATES motor. The analysis of one of the propellant morphologies used in the study of the smaller motor and the white noise surrogate confirm the results of the 15 pound motor. Analysis of the acoustics and the characteristics of the chamber flow correspond with what was previously found. The results from these comparisons show that propellant morphology has a significant effect on the internal chamber flow dynamics.","abstract_html":"This study shows the results of three-dimensional simulations of the chamber flow within the BATES (Ballistic Test and Evaluation System) 15 pound motor.
