NettetInteraction of a Tunnel-like Acoustic Disturbance Field with a Blunt Cone Boundary Layer at Mach 8 The existing measurements of laminar-to-turbulent transition over circular cones in conventional (i.e., “noisy”) hypersonic wind tunnels have established that the transition location moves downstream when the nose radius is increased from zero. . However, … Nettet12. apr. 2024 · I would call it a semi-controlled airflow simulator. A wind tunnel is: (1) a tunnel, (2) generally closed, (3) the airflow is highly controlled, and (4) the device is highly instrumented. The facility at Giga Austin is a mobile unit to get ad hoc measurements at manufacturing facilities rather than sending them out to a real wind tunnel. karloff the appearing https://andygilmorephotos.com
