| 内容記述 | The wake flow field behind the EXPRESS capsule at supersonic speeds is studied experimentally in the wind tunnel. The schlieren photographs and the measurements of the Pitot pressure and the static pressure in the wake clarify the structure of the wake flow field and the effects of the freestream Mach number on it. The wake structure is classified into two types, that is, the subsonic wake neck type and the supersonic wake neck type. The flow characteristics of each wake neck type are discussed. From a viewpoint of the parachute deployment, the effects of the freestream Mach number on the dynamic pressure in the wake are investigated. The recovery ratio of the dynamic pressure in the wake increases with the decrease in the Mach number. At lower Mach number, however, the recovery is delayed due to the extension of the recirculating region behind the capsule bottom. The numerical simulations of the wake flow field are carried out by solving the laminar Navier-Stokes equations and it is pointed out that the recovery of the flow velocity and the dynamic pressure may be enhanced significantly by the turbulent transition on the wake trail. | |||||||||
