Book ChapterDOI
Heat transfer to newtonian and non-newtonian fluids in rectangular ducts
J.P. Hartnett,Milivoje M. Kostic +1 more
TL;DR: In this paper, the authors provide an overview of the analytical and experimental hydrodynamics and heat transfer studies of Newtonian and non-Newtonian fluids in laminar and turbulent flow through rectangular tubes.
Journal ArticleDOI
Technical note: The yield stress—An engineering reality
J.P. Hartnett,Robert Y. Z. Hu +1 more
TL;DR: In this paper, a simple experiment using the falling ball technique was used to demonstrate unambiguously that a 2500 wppm aqueous Carbopol 960 solution has yield stress.
Journal ArticleDOI
Heat transfer to a viscoelastic fluid in laminar flow through a rectangular channel
J.P. Hartnett,Milivoje M. Kostic +1 more
TL;DR: In this paper, the measured local and mean Nusselt numbers for a viscoelastic fluid in laminar flow through a rectangular channel are found to be much higher than those of a purely viscous fluid or a Newtonian fluid.
Journal ArticleDOI
Non-Newtonian viscosity measurements in the intermediate shear rate range with the falling-ball viscometer
TL;DR: In this article, the authors used the falling-ball experiment to measure the non-Newtonian viscosity in the intermediate shear rate range of a polyacrylamide solution.
Journal ArticleDOI
Heat transfer behavior of Reiner-Rivlin fluids in rectangular ducts
S.X. Gao,J.P. Hartnett +1 more
TL;DR: In this paper, the Reiner-Rivlinear formulation with finite values of the second normal stress coefficient is used to model the flow and a finite difference method is developed to obtain the heat transfer results for the H2 thermal boundary condition for different combinations of heated and adiabatic walls.
