Experimental and numerical study of weak shock wave transmissions through minitubes

Résumé

The aim of this paper is to present an original experimental technique to study weak shock wave in a mini-tube. Thus, we have designed an apparatus, which can be connected to any classical shock tube, in order to characterise high speed flows induced by the shock wave transmission in mini-tubes. We have proposed appropriated measurements based on high speed strioscopy coupled with pressure sensors. Two mini-tube diameters are considered: 1.020 ±0.010 mm and 0.480 ±0.010 mm. We have realized preliminary experimental and numerical campaigns with an incident shock wave Mach number at 1.12 ±0.01. The generation of a micro-shock wave was observable in the two mini-tubes. For the smallest mini-tube, we have found an attenuation of the strength of the shock wave with a decrease of 1.8% of the Mach number.
