Boundary layer solutions are presented to investigate the steady flow
and heat transfer characteristics of a continuous flat surface moving
in a parallel free stream of power-law fluid The equations of motion a
re reduced to nonlinear ordinary differential equations by similarity
transformations. These equations are solved numerically with double pr
ecision, using a procedure based on finite difference approximations.
The results are presented for the distribution of velocity and tempera
ture profiles within the boundary layer. The effects of the power-law
index of fluid on the shear stress at the wall and the rate of heat tr
ansfer are studied. For the same generalised Reynolds and Prandtl numb
ers, power-law fluid parameter, and velocity difference \u(w) - u(infi
nity)\, a greater skin-friction and heat transfer coefficient result f
rom u(w) > u(infinity) than from u(w) < u(infinity). (C) 1996 by Elsev
