On the influence of storage duration on rheological properties of liquid egg products and response of eggs to impact loading – Japanese quail eggs

The present study concerns the numerical analysis of both hydrodynamic and thermal properties of a Herschel-Bulkley fluid flow in a pipe. The flow, which in- volves forced heat transfer convection, is steady and takes place within a pipe of circular cross-section with uniform wall temperature. The Herschel-Bulkley model with the Papanastasiou regularization is used and flow index values of 1 and 1.5 are considered. The study focuses on the effect of neglecting both viscous dissipation and temperature dependence of the fluid consistency on its hydrody- namic and thermal properties. For that purpose, we investigate both wall heating (Br 0) as well as the exponential temperature de- pendence of the consistency. The results show that neglecting both of these pa- rameters results in more than a 50% underestimation of the heat transfer due to the viscous nature of this kind of fluid.

Experimental study of rheological properties of water-carbopol microgel

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.
