TURBULENT HEAT TRANSFER IN LIQUID METALS. FULLY DEVELOPED PIPE FLOW WITH CONSTANT WALL TEMPERATURE

Journal Article · · Intern. J. Heat and Mass Transfer

Nusselt number and temperature profile for low Prandtl number fluids of constant properties flowing in a smooth pipe with constant wall temperature are evaluated. Use is made of the theoretical expression for the ratio of eddy diffusivities for heat and momentum. For practical calculation of film coefficient of heat transfer, an interpolation formula is proposed: N/sub Nu/ = 5 + 0.05 N/sub Pr/ /sup 0.2//sup 5/ N/sub Pe/ 0/sup 0.7//sup 7/, which fits the calculated data with a maximum deviation of less than 11% for N/sub Pr/ < 0.1 and N/sub Pe/ < 15,000. Temperature profiles for several Prandtl and Reynolds numbers are compared with the case of constant wall flux. (auth)
