An experimental investigation of the internal ballistics of solid fuel
ramjets was conducted in order to determine the effects of inlet step size,
inlet velocity and wall blowing on flow characteristics behind a backward
facing step inlet.
It was shown that the reattachment point (zone) moves toward the step
inlet with wall mass addition at a constant inlet mass flux. For a given
step inlet, however, the leading edge of the reattachment zone was stationary with variations in inlet velocity. A point where the wall
temperature and centerline static pressure profiles leveled off simultaneously
was defined as the end of the reattachment zone. This zone spread
out (grew thicker) both with increasing inlet velocity for a given step
size, and with increasing step height. Maximum wall temperatures occurred
downstream of the reattachment zone.
