Finite element study of mixed convection for non-Newtonian fluid between two coaxial rotating cylinders

Effects of optical parameters on fluid flow and heat transfer of participating fluid between two vertical coaxial rotating cylinders

“…Unlike most of the earlier cases of the combined rotation and buoyancy in a vertical annulus, in which either the whole system is rotating, or one of the cylinders is rotating but the other is stationary, Venkatachalappa et al [12] conducted a numerical study to investigate the effects of rotation on the axisymmetric flow driven by buoyancy in a vertical annulus with both cylindrical walls rotating at different speeds. More recently, Amoura et al [13,14], Ahmed [15] and Nouar et al [16] turned their attention to Taylor-Couette flow of non-Newtonian fluid with thermal effects. The authors found that the non-Newtonian effects are important on the structure of the flow and the heat transfer.…”

Non Newtonian annular alloy solidification in mould

“…Wang et al [18], studied numerically the natural convection of power law fluids, with the Bingham model, in a saturated porous medium and found that the beginning of natural convection occurs at a minimum fluency value. Amoura et al [19] described, with the mixed finite element, the heat flow and transfer mechanisms in an annular space between two rotating coaxial cylinders, adopting the stress-deformation ratio of Carreau to model the fluid rheological behavior. Luna et al [20] solved analytically and numerically the conjugated heat transfer of a power law fluid in a circular tube, concluding that heat transfer by conduction along the wall is important for estimating the local and global Nusselt number.…”

Experimental correlation of forced convection heat transfer from a NACA airfoil

“…A non-Newtonian flow in an annular space between two coaxial rotating cylinders was studied numerically by Amoura et al [9]. The authors reported effects of varying Reynolds (Re), Grashof (Gr) and Weissenberg numbers (We).…”
