Abstract

Abstract

The mixed spectral method using generalized Laguerre functions for exterior problems of partial differential equations of fourth order was investigated. A mixed spectral scheme was provided for the stream function form of the Navier-Stokes equations outside a disc. Numerical results demonstrate the spectral accuracy in space.
