摘　　要：对平行放置的横向波纹平板形成的通道内的定型层流流动,以壁面波纹的波幅为小量进行了摄动展开,提出了一级近似模型.得到了速度分布的近似表达式,考察了流速和流量与壁面波纹的波幅、波数及上下波纹板的排布相位之间的关系.研究表明,对于波纹通道几何参数的不同组合,流量可能增大,也可能减小.An approximate analytical research on the fully developed laminar flow inside a duct formed with two parallel plates of transverse wavy surfaces was carried out through perturbation on the small amplitude of the wall surface wave.A simple velocity expression was obtained.Effects of the amplitude,wave number and the phase shift of the wavy plate on the flow velocity and flow rate were discussed.Results show that the flow rate might be increased or decreased depending on the interaction of these parameters.
