Heat Transfer for Turbulent Annular Flow of High Prandtl Number Fluids

Document Type

Publication Date



Heat transfer for high Prandtl number fluids flowing turbulently in a concentric circular tube annulus with prescribed wall heat flux is investigated analytically. This surface rejuvenation-based analysis is restricted to thermally and hydrodynamically fully developed flow with constant properties and negligible viscous dissipation. This formulation leads to predictions for the Nusselt Number that are in basic agreement with predictions obtained on the basis of earlier eddy diffusivity models for Prandtl number range from 30 to 1000 and Reynolds number range from 10,000 to 1,000,000.
