摘要：

A new Petrov-Galekin method for the incompressible Navier-Stokes equations is presented. The use of the so-called 'optimal upwind' parameter in multidimensions is justified by a time-scale analysis of the relevant physical processes. The resulting procedure circumvents the Babuska-Brezzi condition and allows equal order interpolation for velocity and pressure to be used.
