PLANE-FLAME SIMULATION OF THE WAKE BEHIND AN INTERNALLY PROPELLED VEHICLE - PART I - SIMULATION OF A SUPERSONIC VEHICLE BY A DETONATION

The development of the flow field behind an internally-propelled vehicle in steady motion at supersonic speed is analyzed by the method of characteristics. The vehicle is simulated by a Chapman-Jouguet detonation propagating in an infinite duct. Friction and heat transfer are accounted for, and the friction factor is related to the heat transfer coefficient through the Reynolds analogy. The characteristic equations are integrated numerically employing a high-speed computer. In the inviscid adiabatic case the flow is nonsteady in all frames of reference. On the other hand, when the effects of friction and heat transfer are included, a region of flow is found to develop which is steady in a frame of reference moving with the detonation front. The steady-flow region starts directly behind the detonation and gradually grows to fill the entire flow field. The flow conditions far downsteam from the detonation return asymptotically to their ambient values. (Author)
