首先，结合空气动力学的边界层原理，针对三角翼边界层分离点检测在实现主动气动控制方面的重要性，讨论了光学式、电容式和热敏式微型剪应力传感器的测量原理和结构方案，选取适合加工条件的微型剪应力传感器样件。 - According to the comparison between simulation results and laboratory measurements , this paper reaches the conclusion that the negative pressure region in convex boundary ( including broken line gradient ) not only caused by boundary layer separation , but also especially caused by centrifugal force which is the result of convex boundary
根据数值计算与模型试验结果的比较，得出具有凸形曲面边界（包括折面底坡）负压区的存在不仅是边界层分离所致，边壁弯曲使过流产生的离心力也是产生负压的重要原因的结论。 - 3 . the characteristics of boundary layer ' s transition , shape and separation are researched . the details as follows : ( l ) airfoil surface is turbulent boundary layer flows ; ( 2 ) velocity figure changed unsteady near the point of boundary layer separation due to randomicity of turbulent flow ; ( 3 ) the airfoil have better state of boundary layer separation and poor stall characteristics because of the upper surface of airfoil is flat
给出了该翼型的附面层特性：翼型表面基本为湍流附面层；在靠近附面层分离位置处，速度型形状、特别是靠近翼型表面的底部速度型形状变化不定，是湍流流动的随机性所致；该翼型具有较好的附面层分离形态，但在失速迎角附近，附面层分离形态变化剧烈、失速特性差，是翼型上翼面形状较为平坦所致。
