浮力不稳定性中性曲线涡量波特征振型 - Around 40 ; the neutral curve obtained by the growth rates of the temperature fluctuation has a ringlike curve separated from the main branch of nachtsheim s calculation by velocity fluctuation at the lower grashof number side ; and its phase velocity is close to the maximum mean velocity where the critical layer of the eigenmode locates . the thermal fluctuation decays rapidly as the nondimensional frequency above 0 . 4 , so that it means that the coupling effect between instability wave generated by buoyancy fluctuation and velocity waves by invicid instability seems weak enough for their critical layers in the range of the nondimensional frequency
详细研究了自然对流边界层中最早失稳的浮力振型的功率谱波长波速与临界层位置等基本特征和它为主导其他振型尚未失稳时按线性理论得到的3种相互独立振型的振幅分布。系统地测量了它所对应的温度和速度涨落的振幅增长规律和中性曲线，实验结果表明，温度涨落的中性曲线在低格拉斯霍夫grashof数 - An experimental investigation on the transition in the boundary layer of horizontal plane with and without single two - dimensional roughness elements has been carried out in the wind tunnel . the distribution in normal and stream - wise directions of intensity of t - s wave excited by vibrating beam was measured in every condition . neutral curves were obtained by measuring the growth of the t - s wave at the normal critical location along the stream - wise direction
在风洞中对水平光滑平板以及加有粗糙元平板的边界层转捩进行了测量与研究，比较了不同情况下平板边界层内由振动梁激励生成的t - s波沿流向和法向强度的分布规律，得到了相应的振型增长曲线以及中性曲线。
