Abstract
The steady magnetohydrodynamics (MHD) flow and heat transfer of an Oldroyd 8-constant fluid with wire coating analysis have been investigated numerically. The wire coating was analysed numerically in the presence of magnetic field with both constant and temperature dependent viscosity. Two different methods namely Reynolds model and Vogel’s model were considered for temperature dependent viscosity. The non-dimensional resulting flow and heat transfer differential equations were numerically solved using Runge-Kutta fourth order method followed by shooting technique and the effects of pertinent physical parameters are shown in graphs. The result of the present study was compared with the earlier published result as a particular case. The non-Newtonian properties of fluid were favourably enhancing the velocity in combination with temperature dependent variable viscosity and two layer variations are remarked in the case of pressure dependent constant parameter for both the cases of constant and varying viscosity which retards the temperature at all points.
