Summary

TRANSIENT HEAT TRANSPORT IN COUNTERFLOWING HELIUM II WAS INVESTIGATED EXPERIMENTALLY INA RECTANGULAR CHANNEL WITH A 26 X 26 MM CROSS SECTION. IT IS SHOWN THAT, WITH INCREASING INPUT HEAT FLUX, THE COUNTERFLOW VELOCITY AND, HENCE, THE INTERNAL HEAT FLUX REACHES A MAXIMUM DEPENDENCE ON THE FLOW PARAMETERS, WHICH LEADS TO ASTRONG INCREASE OF TEMPERATURE IN THE REGION CLOSE TO THE HEATER (AND MAY CAUSE THERE EVEN EVAPORATION OR A PHASE CHANGE TO HELIUM I).
