Abstract. Laminar free convection flow of a power
law fluid from a horizontal plate has been considered. Using Karmana-Pohlhausen
integral method it has been shown that similarity solutions exist if n=1 and if
the difference between the wall temperature and ambient fluid temperature varies
as the cube root of the distance along the horizontal plate. The velocity and temperature
distributions are obtained for different values of flow index n and
parameter R1. It has been observed that increase in the parameter R1 leads to decrease
in the boundary layer thickness and temperature. The velocity rate of heat transfer
and shear stress at wall increases as the parameter R1 increases
in the range O .5 s R1 s 1.5. The velocity at a given point within a thin
liquid layer increases with the increase in the value of a vertical distance yb,
but outside this layer the velocity decreases.
