Abstract:
A liquid fueled, pulsed electric discharge was studied to identify the energy exchange and mixing processes occurring between the liquid, vapor, and plasma components. Liquid water, injected into a small bore 3.5-5.0 mm diameter capillary tube, was subjected to power pulses of up to 5 MW for 15-60 mus duration. Experiments were performed with a variety of discharge and liquid injection conditions. A complex, highly transient sequence of heating and vaporization events occurs as revealed in detailed studies of the plasma optical emissions and resistivity. A 1-D, one fluid model was developed and numerical simulations were performed to help isolate the basic physical processes dominating the discharge dynamics.
