Summary

THE PROPAGATION OF A SECOND SOUNDWAVE AND THE EVOLUTION OF A FINITE AMPLITUDE THERMAL WAVE INTO A SHOCK WAVE WERE SIMULATED BY APPLYING THE FINITE DIFFERENCE SCHEME TO THE TWO-FLUID EQUATION FOR SUPERFLUID HELIUM. TYPICALLY, A FRONT SHOCK, A BACK SHOCK AND A DOUBLE SHOCK WERE WELL SIMULATED. THE RESULTS, HOWEVER, SUGGESTED A NEED TO INTRODUCE THE EFFECT OF THE INTERACTION OF A FLOW FIELD WITH A TANGLED MASS OF QUANTIZED VORTICES TO THE GOVERNING EQUATION IN THE BREAKDOWN STATE.
