Hydrodynamic and thermal characterization of the flow of a Herschel-Bulkley fluid in a pipe
TLDR
In this paper, the numerical analysis of hydrodynamic and thermal characteristics of the flow of an incompressible Herschel-Bulkley fluid of constant physical and rheological properties is presented.Abstract:
The present study concerns the numerical analysis of hydrodynamic and thermal characteristics of the flow of an incompressible Herschel-Bulkley fluid of constant physical and rheological properties. The flow takes place within a horizontal pipe of circular cross section. The pipe is maintained at uniform parietal temperature and is the seat of forced convection heat transfer. Because of the viscous character of this type of fluid, viscous dissipation is taken into account.read more

On the influence of storage duration on rheological properties of liquid egg products and response of eggs to impact loading – Japanese quail eggs
TL;DR: In this paper, the effect of the storage duration on the rheological behavior of liquid egg products (egg yolk, egg white and whole liquid egg) was studied using a concentric cylinder viscometer.

Viscous dissipation effect on the flow of a thermodependent herschel-bulkley fluid
TL;DR: In this paper, the effect of neglecting both viscous dissipation and temperature dependence of the fluid consistency on its hydrody-namic and thermal properties is investigated. But the results show that neglecting these two properties results in more than a 50% underestimation of the heat transfer due to the viscous nature of this kind of fluid.

Effect of storage duration on the rheological properties of goose liquid egg products and eggshell membranes
TL;DR: The eggs of geese were stored for one, 2, 3, 4, 6, and 8 wk at a constant temperature 4°C and the rheological behavior of liquid egg products was studied using a concentric cylinder viscometer.

On creeping drag flow of a viscoplastic fluid past a circular cylinder: wall effects
TL;DR: In this article, the creeping drag flow of a Bingham plastic past a circular cylinder kept symmetrically between parallel plates was analyzed via numerical simulations with the finite element method, where the emphasis was on determining the extent and shape of yielded/unyielded regions along with the drag coefficient for a wide range of Bingham numbers.

Thermal convection for a thermo-dependent yield stress fluid in an axisymmetric horizontal duct
TL;DR: In this paper, the authors considered the combined forced and free convection heat transfer of a yield stress fluid in a horizontal duct heated uniformly with a constant heat flux density, and quantified the effect of the rheological properties on the magnitude of the secondary flows induced by the thermo-dependency of K* and ρ.

TL;DR: In this article, Papanastasiou's viscoplastic model is used with an appropriate modification, which applies everywhere in the flow field in both yielded and practically unyielded regions, to find limiting drag values for cessation of motion of the object in steady flow.
