PLANE-FLAME SIMULATION OF THE WAKE BEHIND AN INTERNALLY PROPELLED VEHICLE. PART 2. SIMULATION OF A SUBSONIC VEHICLE BY A HEAT SOURCE

The development of the flow field about an internally-propelled vehicle in steady motion at subsonic speed in a tube is analyzed by the method of characteristics. The vehicle is simulated by a heat source releasing heat at a constant rate and moving through an infinite duct at a constant subsonic velocity. Friction and heat transfer are accounted for, and the characteristic equations are integrated numerically employing a high-speed computer. In a vehicle-fixed frame of reference the induced flow field is initially steady, but friction and heat transfer soon cause it to become nonsteady. As time progresses, the nonsteady effects slowly decay and the flow field asymptotically approaches a steady state. (Author)
