Dynamic switching of a bistable wall attachment amplifier with short pulse duration
Abstract
Small-scale models with short-duration input pulses are employed to investigate the dynamic switching behavior of a bistable wall-attachment amplifier. Smoke from dry ice is adopted as the flow visualization technique. Results of the study indicate: pressure distributions measured along the inclined walls can provide information on the location of the vent and splitters; the switching may be considered to be dependent only on the strength of the input pulse; switching time is not affected by pulse width; and for very short pulse widths, the switching is a combination of contacting-both-walls and critical-attachment-angle modes of switching.
