Nt. Obot et al., EFFECT OF PRANDTL NUMBER ON SMOOTH-TUBE HEAT-TRANSFER AND PRESSURE-DROP, International communications in heat and mass transfer, 24(6), 1997, pp. 889-896
Heat transfer and pressure drop results in laminar, transitional and t
urbulent flow are presented for the 0.7 to 126 Prandtl number range. T
he working fluids for the experiments were air, water, ethylene glycol
and ethylene glycol/water mixtures. For air or water, the Reynolds nu
mber was varied between 600 and 50,000, while tests with pure glycol a
nd glycol/water mixtures covered the 200-3,000 and 200-10.000 Reynolds
number range, respectively. (C) 1997 Elsevier Science Ltd.
