Figure 9 Effects of different values of \(\Pr\) on temperature
profiles
conclusion
The magnetohydrodynamic stagnation-point flows of a Casson fluid towards
a convectively heated stretching/shrinking sheet are investigated taking
the buoyancy force into consideration. Using the similarity variables,
the governing differential equations are transformed to ordinary
differential equations and solved numerically by shooting method with
Runge-Kutta Fehlberg integration scheme. The effects of the various
governing parameters were analyzed and the following remarks can be
summarized below.
- The velocity boundary layer thickness reduces with magnetic field
parameter.
- The flow field velocity decreases with increase in Casson parameter\(\beta\) as well as the thermal boundary layer thickness.
- The Biot number decreases the thermal boundary layer thickness whereas
the Eckert number increases it.
