Abstract: The general features of flow in converging-diverging nozzle with water addition areinvestigated. water is injected at down stream of the throat in order to keep throat critical when theback pressure is changed. With control-volume methane a model is developed under the assumption ofsteady one-dimensionnal and numerical solution is obtained.
