Pagination or Media Count:
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 Heads entrainment equation with power law profiles and Magers cross flow assumption. In comparison with upwinding differencing, the new scheme has better stability properties, smaller truncation error, and smaller artificial viscosity.
