Abstract
The prime objective of the present study was to examine the effect of temperature dependent viscosity on the revolving axi-symmetric laminar boundary layer flow of 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 were firstly converted into the ordinary differential equations using well known similarity transformations and later, the popular finite difference method was employed to discretize the non linear coupled differential equations. These discretized e-quations were then solved using Newton method in MATLAB, for which an initial guess was made with the help of Flex PDE Solver. Along with the velocity profiles, the effects of temperature dependent viscosity were also examined on skin friction, heat transfer and the boundary layer displacement thickness. The results, so obtained, were presented numerically as well as graphically.关键词
