0512 Application of Boundary Layer Approximation to low Reynolds number viscoelastic flow.

Abstract

The boundary layer theory developed for high Reynolds number Newtonian fluid flow is essentially based on the simplification of the N-S equation using the fact that a lateral dimension of the flow field is much smaller than the longitudinal dimension. Hence, it is applied to non-Newtonian vsicoelastic fluid flows with low Reynolds numbers when the geometry of flow field satisfies the same condition.
