LAMINAR NATURAL-CONVECTION ALONG A WAVY VERTICAL PLATE WITH UNIFORM HEAT-FLUX IN NON-NEWTONIAN FLUIDS

In the steady-state laminar natural convection of power-law non-Newton ian fluids, the surface non-uniformities on the boundary layer flow in duced by a semi-infinite surface are investigated. A transformation me thod is applied to study the heat transfer problem. For an example, a sinusoidal surface is used to explain the amplitude of the wavy surfac e effects. The results of dimensionless velocity and temperature profi les are presented graphically for the case of constant heat flux. The effects of Prandtl number, dimensionless amplitude of the wavy plate a nd non-Newtonian flow index are examined in detail.
