Effect of Uncertainties in Physical Properties on Mixed Convection Along a Rotating Vertical Slender Cylinder With Nanofluids Available to Purchase

The present investigation is aimed to study the effects of uncertainties in physical properties on predicting mixed convection alumina-water nanofluid flow and heat transfer characteristics along a rotating vertical slender cylinder. For this purpose, the different models for thermal conductivity and dynamic viscosity which takes into account the effects of particle size, particle volume fraction, nanolayer conductivity and temperature on the steady boundary layer are applied. The transformed set of coupled non-linear partial differential equations for the single phase nanofluid model is solved by robust Finite Element Method. The influence of various pertinent parameters on velocity profile, temperature profile and on Nusselt number are shown graphically. Excellent validation of the present numerical results has been achieved with earlier published results. It is also found that the Nusselt number increases nonlinearly with the increase of nanoparticle loading for the KKL model which correlates strongly with experimental findings.
