Summary

THE PROBLEM OF PREDICTING THE RATE OF HEAT TRANSFER THROUGH THE WALL OF A DUCT IN WHICH A NON-NEWTONIAN FLUID IS FLOWING IN LAMINAR REGIME IS ANALYZED. THE EFFECT OF HEAT GENERATION BY VISCOUS DISSIPATION IS ALSO CONSIDERED. AN ALTERNATIVE ROUTE, TO DEDUCE AN EXTENSION OF THE LEVEQUE SOLUTION, IS PRESENTED UP TO TERMS INCLUDING THE EFFECT OF THE BRINKMAN NUMBER. THE RESULTS ARE COMPARED WITH PREVIOUS RESULTS SHOWING THAT THE AUTHOR'S EXPRESSION, VALID FOR PIPES AS WELL AS FLAT DUCTS, PRODUCES EXTREMELY GOOD RESULTS WITHIN THE RANGE OF VALIDITY OF THE VARIABLES WHICH IS SPECIFIED.
