Abstract: | In this paper, heat transfer characteristics of a two-dimensional steady hydromagnetic natural convection flow of a micropolar
fluid passed a non-linear stretching sheet taking into account the effects of a temperature-dependent viscosity and variable
wall temperature are studied numerically for local similarity solutions by applying the Nachtsheim-Swigert iteration method.
The results corresponding to the dimensionless temperature profiles and the local rate of heat transfer are displayed graphically
for important material parameters. The results show that in modeling the thermal boundary layer flow with a temperature-dependent
viscosity, consideration of the Prandtl number as a constant within the boundary layer produces unrealistic results and therefore
it must be treated as a variable rather than a constant within the boundary layer. The results also show that the local rate
of heat transfer strongly depends on the non-linear stretching index and temperature index. |
