    摘要: Two systematic wind tunnel tests were conduct to investigate coherence characteristics of fluctuating wind
    pressures along the meridian on hemispherical domes due to Reynolds number effect and roof curvature effect.
    Reynolds number was first alternated from 6.6×104
    to 1.9×106
    under smooth and boundary layer flows. Rootcoherences
    with respect to frequency and location were calculated to show how the Reynolds number effect
    changes the coherence distribution, especially when in approaching turbulent flows. Secondly, the roof curvature
    of the hemispherical dome was changed by f/D (height/span) from 0.5 to 0.1 to see the roof curvature effect. A
    modified form proposed by Hui et al (2009) was applied to present a more compact observation in a parametric
    study way rather than by Davenport’s proposed. It was finally concluded that not only the location of the
    pressure but also the distance between two taps, can significantly determine the distribution features of
