Experiments with a 1:4.2 model of a commuter aircraft with riblets in a large wind tunnelility, with deviations in the drag measurements of up to 3% of nominally identical conditions. This discrepancy was independent of the riblet film and was probably caused by lacking reliability of the wind tunnel balance. Nevertheless, the data show drag reductions by 1–6% with riblet film.

High resolution conformal mesh computations for V, U or L groove riblets in laminar and turbulent botal data. Conformal mesh computations for semi-circular U, L, and intermediate form, riblets indicated a similar drag reduction in laminar flow, but also revealed important differences in the spanwise distribution of Cf across these riblets compared to the V-groove type.

Review: effect of the OLDs on near wall coherent structures; discussion and need for future worky decreasing the strength of the developing hairpins. Since the outer layer devices reduce the effect of a large scale structure by shedding vorticity of opposite sign, and the break up of the near wall structures depends to some extent on the outer layer disturbances, it is possible that there is a作者: Coronation 時(shí)間: 2025-3-24 08:31 作者: 窒息 時(shí)間: 2025-3-24 11:35 作者: 四牛在彎曲 時(shí)間: 2025-3-24 15:32

The correlation of added drag with surface roughness parametersnctions with surface geometry is then discussed and the most recent results described. Possible future developments are outlined to eliminate fouling, reduce roughness to the ‘hydraulically smooth’ datum and then to further reduce drag noting that most fish do not foul and there is some evidence of drag reducing mechanisms.作者: Amylase 時(shí)間: 2025-3-26 13:40 作者: folliculitis 時(shí)間: 2025-3-26 19:46
Heat transfer study of ribletsf increasing the drag. During the experiment, the heat loss due to thermal radiation was shown to be significant at lower Reynolds numbers. An attempt has been made to nullify this loss by heating the surrounding walls to the same temperature as the test surface.作者: 蛛絲 時(shí)間: 2025-3-26 22:10
Performances of internal manipulators in subsonic three-dimensional flowshord Reynolds numbers have been considered: 2.65 10. and 4.25 10.. On both sides of the aerofoil, grooves have been aligned with the free-stream flow direction. Skin-friction drag decreases of up to 5–6% have been recorded when the dimensionless rib height, scaled with wall units, is less than 15–20.作者: hereditary 時(shí)間: 2025-3-27 02:52
Turbulent drag reduction of a d-type rough wall boundary layer with longitudinal thin ribs placed wiin terms of the rib Reynolds number. Comparisons of some mean flow properties between the d—type rough wall flow with and without the longitudinal ribs provide evidence that the present passive control device also reduces the turbulent energy production rate.作者: Afflict 時(shí)間: 2025-3-27 05:34
Experiments with a 1:4.2 model of a commuter aircraft with riblets in a large wind tunnel Tunnel (DNW). 82% of the aircraft model including large parts of the wings and the nacelles were covered with the riblet film. The leading edge of the wing, however, was covered with smooth plastic film.
