Summary

TWO TYPES OF SECONDARY HEAT SOURCE HAVE BEEN USED. IN THE FIRST CASE, THE HEAT LEAK THROUGH THE VESSEL WALLS INTO THE POOL WAS VARIED WITHOUT CAUSING NUCLEATION, SO AS TO RETAIN CONVECTIVE HEAT TRANSFER ; THE CONVECTIVE FLOW LOOPS INDUCED IN THE POOL PRODUCED A SMALL ENHANCEMENT OF THE HEAT TRANSFER FROM THE CYLINDRICAL HEATER. IN THE SECOND CASE, A SMALL HORIZONTAL HEATER LOOP WAS INTRODUCED INTO THE POOL BELOW THE CYLINDRICAL HEATER SO THAT BOILING OCCURRED AT THE LOOP TO GIVE RISING BUBBLES. THIS PRODUCED A LARGE ENHANCEMENT OF THE CONVECTIVE HEAT TRANSFER.
