The buoyancy-driven boundary-layer flow from a heated horizontal circular cylinder immersed in a water-based alumina (Al2O3) nanofluid is investigated using variable properties for nanofluid viscosity. Two different viscosity models are utilized to evaluate heat transfer enhancement from a cylinder. Exact analytic solutions of the problem are attained employing a novel...

We propose and analyse an augmented mixed finite element method for the Oseen equations written in terms of velocity, vorticity, pressure with non-constant viscosity homogeneous Dirichlet boundary condition velocity. The weak formulation includes least-squares arising from constitutive equation incompressibility condition, we show that it satisfies hypotheses Babu\vska-Brezzi theory. Repeating ...

The problem of magnetohydrodynamic flow and heat transfer of a viscous, incompressible, and electrically conducting fluid past a semi-infinite unsteady stretching sheet is analyzed numerically. The problem was studied under the effects of Hall currents, variable viscosity, and variable thermal diffusivity. Using a similarity transformation, the governing fundamental equations are approximated b...
