摘要

The high frequency behaviour of the fluid velocity patterns for smooth and corrugated pore channels is studied. For wedge-shaped pore geometries, the classical approach is modified by a non-analytic extension proposed by Achdou & Avellaneda (1992). The dependency of the non-analytic extension on the apex angle of the wedge was derived. Precise numerical computations for various apex angles in two- dimensional channels confirmed this theoretical dependency, which is somewhat different from the original Achdou & Avellaneda predictions. Moreover, it was found that the contribution of the wedge-shaped singularities does not alter the parameters of the classical theory by Johnson et al. (1987).
