TURBULENT HEAT TRANSFER IN DRAG-REDUCING FLUIDS
An analytical method based on the analogy between energy and momentum transport in turbulent flow was developed for predicting the heat transfer in turbulent pipe flow of non-Newtonian drag-reducing fluids from the frictional characteristics of the fluid. The use of Meyer's correlation for predicting the friction factor and sublayer thickness of drag-reducing fluids permits the heat-transfer rates for such fluids to be determined from simple measurements of the pressure drop and flow rate. Nusselt numbers predicted by this method deviated by plus 8.5% avg from published experimental heat-transfer data for water for 10,100, and 1000 ppm aqueous solutions of Dow Chemical Co.'s Separan AP-30 drag-reducing additive. The heat-transfer analysis predicts that a reduction in the friction factor will be accompanied by a reduction in Nusselt number for a given Reynolds number and for Prandtl numbers greater than 1.
