Web12 Apr 2024 · Vortex generators (VGs) are a passive method by which to alleviate boundary layer separation (BLS). The device-induced streamwise vortices propagate downstream. There is then lift-off from the surface and the vortex decays. The effectiveness of VGs depends on their geometrical configuration, spacing, and flow characteristics. In a high … Web•The flow accomplishes this via the increase of static pressure across the shock wave and the pressure increase due to the subsonic flow in the remaining diverging section. •As … Web13 May 2024 · As a subsonc flow is contracted, the velocity and Mach number increase. When the velocity reaches the speed of sound (M = 1), the flow chokes and the Mach number can not be increased beyond M = 1. We want the highest possible velocity in the test section of the wind tunnel. hydration rate

WebDescription SUBSONIC WIND TUNNEL 305 mm Air enters the tunnel through an aerodynamically designed effuser (cone) that accelerates the air linearly. It then enters the working section and passes through a grill before moving through a diffuser and then to a variable-speed axial fan. The grill protects the fan from damage by loose objects.
