NEW TRANSFER AND FRICTION FACTOR CORRELATIONS FOR WALL HEATING AND/OR COOLING OF VISCOUS FLUIDS WITH HIGH TEMPERATURE DEPENDING OF THEIR VISCOSITIES VERSUS TEMPERATURES, UNDER LAMINAR FLOW CONDITIONS.

CORRELATIONS TRANSFERT/FACTEUR DE FROTTEMENT POUR LE CHAUFFAGE/REFROIDISSEMENT D'UN FLUIDE VISQUEUX A FORTE DEPENDANCE THERMORHEOLOGIQUE EN ECOULEMENT DE CONDUITE EN REGIME LAMINAIRE.

Summary

THE AUTHORS PRESENT TEST RESULTS FOR HEAT TRANSFER IN HEATING/COOLING AND ASSOCIATEDPRESSURE DROPS OBTAINED ON TWO NEWTONIAN VISCOUS FLUIDS IN LAMINARY FLOW. THESE FLUIDS (AQUEOUS SOLUTION OF GLYCEROL AND LUBRICATING OIL) WERE SELECTED FOR THEIR HIGHLY TEMPERATURE DEPENDENT VISCOSITY. AN ORIGINAL CORRELATION OBTAINED FOR THE FRICTION FACTOR IS GIVEN, CONFIRMING THE SIGNIFICANCE OF HEAT TRANSFER ON PRESSURE DROP IN DUCTS.
