  TWO-FLUID MODEL OF JETS MIXING IN A DUCT
  2-dimensional (y-z), Cartesian, steady, two-phase, elliptic

  This is an example of the application of the two-fluid model of
  turbulence to non-reacting, turbulent flow in a duct, as
  illustrated:
  ////////////////////////////////////////////////
  Inlet                                       Exit
  --------> W2                         ---------->
  ////////////
         ---------->                    ------->
             /////////////////////////////////////

  In the present calculations, the fluid 1 is defined as that which
  moves away from the stepped wall and fluid 2 as that moves
  towards it respectively. It is postulated that only fluid 2 enters
  the duct at the inlet, and that it is converted into fluid 1 there
  by entrainment. The boundary condition employed here is an extreme
  one to emphasise the role of inter-fluid transport of mass and
  momentum.
