  SIMULATION OF THE LONGWELL BOMB

  2-dimensional (x-y), polar, steady, elliptic simulation


  This case simulates the experiment of Longwell, Frost and Weiss
  used to produce the 'ranking' of fuels for gas turbines. The
  apparatus is a refractory sphere, into the centre of which fuel
  and air are injected through many small holes. The exhaust
  products escape through fewer, larger holes in the shell. The
  gases, which are highly turbulent as a consequence of the high
  injection velocities, burne within the sphere.

  The apparatus approximates a fully-stirred, adiabatic, steady-flow
  reactor.
