1、前言奇点分布法应用于流体工程学的研究,能使人们很好理解现有的许多成果。也就是说,Birnbaum把无限薄的薄翼换成旋涡分布而导致薄翼理论,Clauert进一步使这一理论通用化,Munk在薄翼面上引入源、汇,规定着这些旋涡和源、汇分布情况,让它们满足翼面上的边界条件。这种方法Schlichting等人在直列叶栅里、Acosta等人 1, Foreword Singular point distribution method applied to fluid engineering research, can make people well understand the many existing results. That is to say, Birnbaum changed the thin wing to the vortex distribution and led to the thin wing theory. Clauert further made this theory universal. Munk introduced sources and sinks on the thin airfoil, which stipulated these vortices and sources. The situation, let them meet the boundary conditions on the airfoil. Schlichting et al.
