stall angle meaning in Chinese
失举迎角
失速角
Examples
- The effect of reynolds number on rudder hydrodynamic performance is also analyzed . up to the stall angle the computed lift and drag agree well with measurements and other author ' s calculations , whereas stall angle , lift and drag beyond the stall angle are slightly under - predicted . the solver is used to investigate laminar and turbulent separated flows around a 6 : 1 prolate spheroid at high incidence angles and their effects on hydrodynamic forces
应用所开发的求解器，以naca0015翼型舵为算例计算了船舵在不同雷诺武汉理三;大学博士学位论文数下大舵角范围内的三维粘性流场及水动力，成功地预报了舵的失速角和最大升力，并初步探讨了雷诺数对舵水动力的影响;计算结果与现有试验和计算数据比较，吻合程度相当好，初步检验和验证了该求解器精确模拟粘性流动和计算水动力的能力。 - Firstly , the airfoil ' s classic flutter ( at small attack angle ) , stall flutter ( near the static stall angle ) and response ( at large attack angle ) are analyzed . it is found from the numerical results that " lock - in " will occur at certain freestream velocity range near the static stall angle , where the frequency of the vortex will be equal to the natural frequency and the flutter has the characteristic of self - induced oscillation . when the attack angle is far from the static stall angle , the vortex will have its own frequency , which differs from the natural frequency , and the flutter has the characteristic of forced oscillation
首先研究了二维翼型的古典颤振(小攻角) 、失速颤振(失速攻角)和动力响应问题(大攻角) ，得到以下结论：在静态失速攻角附近的一定来流速度范围内，分离涡会发生频率锁定现象，分离流的频率与固有频率趋于相同，这时的振动呈现自激振动的特点；远离失速攻角时分离流频率则摆脱固有频率的影响，此时的振动具有强迫振动的特点。
