Such a device could be useful in pure research for studying turbulence, and in applied research for testing models much as is done in a water tunne978-1-4612-7799-6978-1-4612-3108-0作者: 直言不諱 時間: 2025-3-22 02:02 作者: Oligarchy 時間: 2025-3-22 06:47 作者: FUME 時間: 2025-3-22 09:19 作者: 充滿裝飾 時間: 2025-3-22 13:18

Cryogenic Wind Tunnelsmic testing experience in the NASA Langley 0.3-m Transonic Cryogenic Tunnel (TCT). Since we built the 0.3-m TCT in 1973, it has logged over 8000 hours of running at cryogenic temperatures. We use the 0.3-m TCT for aerodynamic testing and to develop test techniques for cryogenic tunnels..Areas briefl作者: 最后一個 時間: 2025-3-23 14:09 作者: kyphoplasty 時間: 2025-3-23 20:51

Micro and Macroturbulence in Superfluid Heliumns where it has been traditionally applied. The main physical issues in formulating these kinds of problems are how the microturbulence interacts with the two velocity fields that describe the flow of superfluid helium to modify the macroscopic turbulence, and how this large scale turbulence acts back on and sustains the microturbulence.作者: 上腭 時間: 2025-3-30 15:53 作者: 寬敞 時間: 2025-3-30 19:29
