Title:
Experimental Investigation of a Line-Cavity System Equipped with Fiber-Optic Differential Pressure Sensors in a Shock Tube 
Abstract:
The aerodynamic behavior inside a line-cavity system is investigated within this work. Acoustic effects, like attenuation and resonance, are mainly dependent on the geometric line-cavity system properties: radius r, line length L and cavity volume V. In order to determine the transfer function from the system entry to the location of the pressure sensor at the cavity end, newly developed fiber-optic differential pressure sensors are used to acquire signals of high bandwidth. In contrast to appro...    »
