  • 例句与用法
  • 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。
  • In this paper , the boundary layer characteristics of a supercritical airfoil is researched in wind tunnel . from the start to control boundary layer separation and to improve aerodynamics characteristics of this airfoil , three kinds of trapezoid , delta and airfoil shaped vortex generators are designed based on traditional , sub boundary layer and micro - vortex generators conceptual design . it include as follows : 1
    研究工作中,从控制该翼型附面层分离、提高大迎角气动性能的角度出发,通过风洞实验研究,研究了该翼型的附面层特性和气动性能,针对其附面层特性,给出了梯形、三角形和翼型式三种涡流发生器设计方案,为下一步研究工作奠定了坚实基础。
  • Three kinds of trapezoid , delta and airfoil shaped vortex generators are designed based on traditional , sub boundary layer and micro - vortex generators conceptual design , to study the influence of the shape , height , aspect ratio , chordwise position , spanwise position and direction angles of vortex generators on boundary layer separation control
    ( 5 )综合分析研究了涡流发生器的工作原理和设计原则。根据国内外资料,研究了涡流发生器形状、高度、展弦比、尖削比、弦向位置、展向位置和方位角等因素对附面层分离控制效果的影响。
