The laminar boundary layer on a moving continuous flat sheet immersed in a non‐Newtonian fluid

Abstract

Abstract The laminar boundary layers on a moving continuous flat surface in non‐Newtonian fluids characterized by the power law model are investigated using exact and approximate methods. Both pseudoplastic and dilatant fluids are considered. Numerical solutions of the boundary‐layer equations are obtained for values of the parameter n in the power law model ranging from 0.1 to 2.0. An integral solution of the momentum equation, which can be used to obtain values of the dimensionless shearing stress that are in good agreement with the exact values, is developed. An integral solution to the energy equation is also presented.
