The free convective boundary layer flow induced by a uniform temperature semi-infinite vertical surface embedded in a porous medium is considered. Particular attention is paid to how inertial effects (form drag or Forchheimer) combine with a spanwise pressure gradient to affect the otherwise two-dimensional flow. The resulting flow is three-dimensional but self-similar. The boundary layer equations are supplemented by an algebraic equation governing the magnitude of the spanwise velocity field. The modifications required to solve this problem using the Keller box method are described. It is found that inertial effects serve to inhibit the spanwise flow near the heated surface.
