Effect of temperature dependent viscosity on revolving axi-symmetric ferrofluid flow with heat trans

The prime objective of the present study is to examine the effect of temperature dependent viscosity μ(T) on the revolving axi-symmetric laminar boundary layer flow of an incompressible,electrically non-conducting ferrofluid in the presence of a stationary plate subjected to a magnetic field and maintained at a uniform temperature.To serve this purpose,the non-linear coupled partial differential equations are firstly converted into the ordinary differential equations using well-known similarity transformations.The popular finite difference method is employed to discretize the non-linear coupled differential equations.These discretized equations are then solved using the Newton method in MATLAB,for which an initial guess is made with the help of the Flex PDE Solver.Along with the velocity profiles,the effects of temperature dependent viscosity axe also examined on the skin friction,the heat transfer,and the boundary layer displacement thickness.The obtained results are presented numerically as well as graphically.
