Summary

AN INVESTIGATION HAS BEEN CONDUCTED TO CLARIFY FOULING EFFECTS OF GEOTHERMAL WATER SCALE DEPOSITED ONTO A HEATING SURFACE UPON ITS FORCED CONVECTION HEAT TRANSFER CHARACTERISTICS. EXAMINED IS A CIRCULAR CYLINDER, ON WHICH PARTICLES OF SILICA SCALE HAVING FOUR DIFFERENT SIZES ARE UNIFORMLY DISTRIBUTED. THE REYNOLDS NUMBER WAS VARIED FROM ABOUT 4,500 THROUGH 50,000. LOCAL AND MEAN HEAT CHARACTERISTICS WERE MEASURED AS FUNCTIONS OF PARTICLE SIZE AND REYNOLDS NUMBER. SUBSEQUENTLY THE MEAN FOULING RESISTANCE WAS ESTIMATED FROM THOSE RESULTS, COMPARED WITH OTHER EXPERIMENTS, AND ITS CHARACTERISTICS ARE CLARIFIED.
