Forced convection heat transfer from a sphere to non‐Newtonian power law fluids

Laminar natural convection from a heated square cylinder immersed in power-law liquids

“…Similarly, shear-thickening behaviour can impede the rate of heat transfer by up to about $ 30-40%. These trends are qualitatively similar to that seen for a cylinder and a sphere in free convection regime [22,23] as well as in forced convection regime [44,59]. Based on our previous results for a cylinder and a sphere [22,23], the present numerical results can be adequately correlated by the following functional relationship:…”

Steady forced convection heat transfer from a heated circular cylinder to power-law fluids

“…Similarly, there have been a few studies on the sedimentation of cylinders in powerlaw fluids [42,43], but the main thrust of these studies was to develop drag correlations. Finally, there have been a few numerical studies on the forced convection heat transfer to power-law fluids from a square cylinder [44,45], from a sphere [46] and from tube banks [47].…”

Numerical simulation of heat transfer in aseptic processing operations involving non-Newtonian fluids

“…They observed that the effect of particle to tube diameter on fluid to particle heat transfer coefficient was not clear cut. Dhole et al (2006) studied the forced convection heat transfer from a sphere in unconfined non Newtonian power law fluids and suggested further work in this field is required to explore the roles of temperature dependent properties and confining tube wall effect. The ranges of conditions studied by them were 5  Re  200, 1  Pr  400 and 0.5  n  2.…”

“…Here Re is the particle Reynolds number, Pr is the Prandtl number and n is the power law index. Correlations for the average Nusselt number has been proposed by Dhole et al (2006) at two different boundary conditions viz. constant temperature and constant heat flux at the sphere surface.…”
