Abstract

Ignition delay of hypergolic bipropellants of TMEDA and WFNA by their binary droplet collision has been experimentally studied, with the particular emphasis on the effects of impact parameter, B, which measures the deviation of the collision from the trajectory of head-on situation. The experimental results reveal a non-monotonic effect of the impact parameter. For B slightly larger than 0, the intrinsic deformation and internal flow pattern promote the mixing between the colliding droplets and hence reduce the ignition delay. If B increases to so that off-center separation happens, the hypergolic ignition would be prolonged owing to the less mass transfer.
