Laminar Flow in a Two-Dimensional Channel with a Right Angle Corner.

Abstract

Laminar, steady, incompressible flow in a two-dimensional channel with a right angle corner was investigated by numerical analysis and experimental measurement. The problem was used as a vehicle to compare a finite differencing method with an upwind differencing scheme. From the numerical solutions, zones of separated flow in the outside (reentrant) corner were found at all Reynolds numbers investigated. A second separation region, extending downstream from the inside (salient) corner was found. Several different methods of formulating the vorticity at the salient corner were investigated. Experimentally measured velocity profiles and smoke photographs of the separation regions indicated reasonable agreement with calculated solutions. (Modified author abstract)
