Abstract对不可压缩层流二维干扰流动,本文提出一个干扰流动(IF)理论。IF理论要点为:1)干扰流动沿主流的法向被分为三层即粘性层、干扰层和无粘层,引进了法向动量交换为主导过程的干扰层概念。2)利用力学守恒律、三层匹配关系及文中引进的干扰模型,把三层的空间尺度及惯性-粘性诸力的数置级表示为单参数m的函数,m<1/2•3)导出描述各层流动的控制方程、导出描述全城流动的控制方程为简化Navie-Stokes(SNS)方程。IF理论适用于不存在分离的附着干扰流动以及存在分离的大范围干扰流动,经典边界层(CBL)理论和流动分离局部区域Triple-Deck(TD)理论分别是本文理论在参数m=O和1/4时的两个特例,本文理论容易推广到可压缩、三维及湍流流动。
