  Dual Scattering Channel schemes generalise Johns' TLM algorithm and replace
the latter in situations where the transmission line picture of wave
propagation fails. This is notoriously the case in applications to fluid
dynamics, for instance. In this paper, a DSC numerical solution of the
Oberbeck-Boussinesq equations is presented, which approximate the Navier-Stokes
equations for viscous quasi incompressible flow with moderate variation in
temperature.
