boundary layer separation造句
例句與造句
- 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
根據(jù)數(shù)值計(jì)算與模型試驗(yàn)結(jié)果的比較，得出具有凸形曲面邊界（包括折面底坡）負(fù)壓區(qū)的存在不僅是邊界層分離所致，邊壁彎曲使過流產(chǎn)生的離心力也是產(chǎn)生負(fù)壓的重要原因的結(jié)論。 - 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
給出了該翼型的附面層特性：翼型表面基本為湍流附面層；在靠近附面層分離位置處，速度型形狀、特別是靠近翼型表面的底部速度型形狀變化不定，是湍流流動(dòng)的隨機(jī)性所致；該翼型具有較好的附面層分離形態(tài)，但在失速迎角附近，附面層分離形態(tài)變化劇烈、失速特性差，是翼型上翼面形狀較為平坦所致。 - 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，從控制該翼型附面層分離、提高大迎角氣動(dòng)性能的角度出發(fā)，通過風(fēng)洞實(shí)驗(yàn)研究，研究了該翼型的附面層特性和氣動(dòng)性能，針對(duì)其附面層特性，給出了梯形、三角形和翼型式三種渦流發(fā)生器設(shè)計(jì)方案，為下一步研究工作奠定了堅(jiān)實(shí)基礎(chǔ)。 - 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 )綜合分析研究了渦流發(fā)生器的工作原理和設(shè)計(jì)原則。根據(jù)國(guó)內(nèi)外資料，研究了渦流發(fā)生器形狀、高度、展弦比、尖削比、弦向位置、展向位置和方位角等因素對(duì)附面層分離控制效果的影響。 - It's difficult to find boundary layer separation in a sentence. 用boundary layer separation造句挺難的
