Abstract

Rayleigh's problem of an idealized non-Newtonian fluid past a flat plate has been considered by using the constitutive equation of the power-law model. The velocity profiles can be reduced to a single curve by changing the scale of the axis perpendicular to a flat plate, and the exact solution of the problem can also be generated. Of the pseudoplastic fluid the velocity decreases more slowly than that of the Newtonian fluid, as its distance from the plate increasses. Of the dilatant fluid the velocity decreases faster, and becomes zero at a definite distance from the plate.
