Heat transfer to non-Newtonian fluids in laminar flow through rectangular ducts
TL;DR: In this article, a finite volume technique is used to solve the conservation equations of mass, momentum, and energy of non-newtonian fluids flowing laminarly through rectangular ducts, where the viscoelastic behavior of the fluid is represented by the Criminale-Ericksen-Filbey (CEF) constitutive equation.

Laminar Flow Forced Convection Heat Transfer and Flow Friction in Straight and Curved Ducts - A Summary of Analytical Solutions
Ramesh K. Shah,A. L. London +1 more
TL;DR: Theoretical laminar flow solutions for heat transfer and flow friction are of importance in the development of compact heat exchangers as discussed by the authors, generally the higher the degree of compactness, the lower is the Reynolds number and the greater is the relevance of the theory solutions.
