  DISPLAY
  The problem considered is that of the injection of monopropellant
  droplets through small holes in one end of a rocket motor. These
  droplets burn (i.e undergo a phase change involving the dis-
  appearance of high-density liquid and its replacement by low-
  density gas), at a rate dependent upon the droplet diameter. As a
  consequence, a pressure gradient is set up which accelerates the
  gas and, to a lesser extent, the liquid. Friction between the
  droplets and the gas causes the former at first to deccelerate
  and later a accelerate.

  The main task is to compute the distance from the injector at
  which the propellant is fully consumed, as functions: of the
  injection velocity, of the propellant and combustion-product
  properties, and of a measure of the relative speed of momentum
  and heat transfer.
