Experimental Parameters

Electrode ablation in a rail type of electromagnetic shock tube has been studied. Cathode ablation was found to be present over a wide range of experimental parameters whereas anode ablation was found to be immeasurably small. The parameters varied included the drive current, gas pressure, and the electrode material. Observations of current sheet velocity were interpreted as evaporation of cathode material from cathode spots. The ablation series determined from velocity data for the metals tested was: mild steel, Zn, Cu, Mo, in order of decreasing amount of ablation.

Hot Film

A parametric study was performed to determine the effect of sensor size on the performance of flush-mounted hot-film sensors, operated using constant-temperature anemometry. Three nickel sensors with surfaces of 12.5 × 125 microns, 25 × 250 microns, and 50 × 500 microns were deposited on glass flat-plate substrates. The frequency response and sensitivity of the sensors were measured using both electrical and flow testing. Electrical testing was performed using both sine and square waves. Flow testing was performed in a shock tube by subjecting the flush-mounted sensors to a shock-induced boundary layer. As the sensor size was decreased, frequency response increased and sensitivity decreased. These trends were observed for both electronic and flow testing conditions.
