The knowledge on understanding non-Newtonian fluid dynamics influences and behaviors in magnetic and nanoscale effects of transport is also important to the advanced processes of engineering. The current paper examines MHD flow and heat transfer of a Williamson nanofluid across a stretching cylindrical surface, taking into consideration Hall current and chemical reaction and non-Fourier heat and mass flux that is described by the Cattaneo Christov theory. The transport of Nanoparticles is explained in terms of Buongiorno model of thermophoresis and Brownian movement. Similarity variables are used to transform the governing nonlinear equations and then analytically solved via Optimal Homotopy... More >
