Experimental investigation of first and second-sound shock waves in liquid helium II
Abstract
A gasdynamic shock which propagates through saturated helium vapor and subsequently reflects from the upper surface of a column of LHeII is studied. Highly repeatable arrival time data for the incident gasdynamic shock and the resultant first and second sound shocks in the liquid are discussed. Theoretical predictions that the temperature decreases through the pressure shock and increases through the temperature shock are evaluated. Amplitude measurements based on static detector calibrations are discussed along with temperature jump measurements for the coupled second sound shock.
