Cross Stream Differencing for Integral Boundary Layer Equations.

Abstract

An efficient, stable, explicit, first-order cross-stream differencing scheme having low truncation error is derived and applied to three dimensional integral boundary layer equations. The analysis is considered in detail for the particular case of the momentum integral equations and Head's entrainment equation with power law profiles and Mager's cross flow assumption. In comparison with upwinding differencing, the new scheme has better stability properties, smaller truncation error, and smaller artificial viscosity. Keywords: Boundary layer, Turbulence, Differential equations.
