Incorporation of an Actuator Disc for Lattice Wing Modelling in an unstructured Navier-Stokes Solverce wing as a function of its geometrical characteristics. The numerical results obtained for a lattice wing alone are compared with experimental data for different Mach numbers and angles of attack in order to validate the method.作者: seruting 時(shí)間: 2025-3-22 04:21

Numerical Study of Four-Vortex Aircraft Wakes a strong inner vortex pair. The investigation shows that a strong inner pair is necessary for the instability to cause a large increase of vortex radii of the outer vortex pair. This increase in turn leads to a rapid decay of rolling moment.作者: 倔強(qiáng)不能 時(shí)間: 2025-3-22 10:02

Pressure and heat flux measurements at the surface of an asymmetric cone at Mach number 4.6 in ISL’so create a cone asymmetry. With these models differential interferometry flow visualisations, surface pressure and heat transfer measurements were performed at Mach number 4.6 and 7 km altitude atmospheric conditions at the ISL’s shock tunnel STB to examine the resulting flow around the asymmetric cone model.作者: 蜿蜒而流 時(shí)間: 2025-3-23 22:17
Control of Flow around Bluff Bodies by Passive Wake Ventilation numbers, reaching up to 66% for spheres. High drag reductions were also found for elongated bluff bodies at angle of incidence 5 deg and 10 deg. At zero angle of incidence the ventilation effect decreases with increasing fineness ratio. Pitching moment was enhanced by wake ventilation.作者: angiography 時(shí)間: 2025-3-24 03:54 作者: 彎彎曲曲 時(shí)間: 2025-3-24 07:59 作者: Canary 時(shí)間: 2025-3-24 12:56
Numerical Investigation of the Flow Around Different Slat Tracks on a Swept High Lift Wing Segment For the aircraft track only a minor lift change is found, but also a 20% drag increase.
