Physical Properties and Heat Transfer in Tube Flows of Non-Newtonian Fluids

Department of Mechanical Engineering and Design, Hankuk Aviation University, Kyonggi, Korea

ABSTRACT

A brief summary for non-Newtonian fluids is presented to define the meaningful parameters for the analysis of fluid flow and heat transfer. Rheological models and thermophysical properties for non-Newtonian fluids are summarized for the flow and heat transfer analysis. The characteristic time and the diffusion time of polymer solutions are discussed to stress the significance of the rheological description of non-Newtonian fluids. The crucial roles of the solvent chemistry and degradation on the fluid flows and heat transfer are elucidated. Discussion on heat transfer is focused on the forced convection in tube flows for the power law fluids and viscoelastic fluids. Long thermal entrance length for viscoelastic fluids is discussed extensively.
