Heat transfer to non-newtonian fluids flowing laminarly through rectangular ducts is examined. The conservation equations of mass, momentum, and energy are solved numerically with the aid of a finite volume technique. The viscoelastic behavior of the fluid is represented by the Criminale-Ericksen-Fi

A criterion for stability of laminar flow of purely viscous non-Newtonian fluids is proposed and compared with the criterion of Ryan and Johnson, and Hanks. The proposed criterion is found to be in good agreement with the experimental findings given in the available literature. A generalized relatio
A new analytical approach is presented to estimate the local and mean heat flux from a wall maintainedat a given temperatureto a fluid flowing in a laminarregime. Theprocedurecan beapplied to the analysis of planeas well as cylindrical geometry configurations while the fluid behaviourcan be consider
