| Abstract | ||
| In this paper, a numerical investigation of a natural convection from an isothermal inclined plate immersed in air has been done. Taking into account the variation of the viscosity and thermal conductivity with temperature. The governing conservation equations of continuity, momentum and energy are non-dimensionalized by using an appropriate transformation. The non-dimensionalized equations are solved simultaneously by using a finite volume method. The effect of inclination angle with varying viscosity and thermal conductivity on the local skin friction, local Nusselt number, average skin friction and average Nusselt number has been discussed. From the results obtained the allotment of the local skin friction and the local Nusselt number on the plate vary due to angle change. The average skin friction and the average Nusselt number decrease with increase of the angle of inclination. | ||
