On the approximation of convection problems in fluid dynamics
Abstract
It is well‑known that oscillatory result when cerntral difference of finite element approximations are suoght for convective and boundary layer flows unless the grid length is sufficiently small. A priori limits on the grid spacing, bleow which the solutions are oscullation freee, are derived form one‑dimensional idenlizations of these problems and result form boundaryb layer theiry.
