摘要

In this work, the effect of swirl on regression rate (r_b) in a hybrid rocket motor is investigated numerically. The r_b increased monotonically with inlet swirl number and was also found to depend on the inlet swirl profile. The swirl velocity profiles with the peak closer to the axis yielded higher r_b. Parametric study on fuel grains of various lengths and diameters (i/D < 25) shows that swirl is more effective in improving the average r_b for short grains (L/D < 5) and large diameter grains.
