NACA0012翼型的截面图 由于NACA0012是对称翼型,在下图左侧数据表中仅列出了单边的数据,表中c是弦长(弦长为1.00);x是弦长坐标(单位是x/c);y是对应x位置的翼面与弦的距离(单位是y/c)。 图1 NACA0012翼型数据与截面图 NACA0012翼型的升力曲线图 图2是根据美国的技术资料数据绘制的NACA0012翼型的升力曲线图,在...
1.在profili软件中选择NACA0012翼型(如图) 2.通过E输出得到翼型的数据并添加第三维数都为0,以备倒入gridg网格软(注意:要把尾部衔接触的数据设成统一数据以确保尾部没有开口) 3把上述数据倒入gridg网格软件,效果如图 4处理完后保存为cas文件以备导入fluent用 2 .fluent处理 1 将上述准备好的文件倒入fluent,效果...
简单的梯形机翼,采用NACA0012翼型,具有翼梁、翼肋和蒙皮结构。详细参数如下:翼根弦长3600mm,翼梢弦长1500mm,翼展4500mm,前缘后掠角5度。
The transitional flow past a NACA0012 airfoil at Reynolds numbers, Re, between 50,000 and 140,000 is investigated using experiments and low and high-fidelity numerical simulations. Variations in Reynolds number provide the quasi-steady response of the flow and resulting lift to dynamic inflow (var...
根据仿真结果得到:通风机反转后流场内压力参数变化不大,流场内旋流数目增加0.12,反风风量达到正常风量的64%,符合我国《煤矿安全规程》有关规定,证明了NACA0012翼型在矿用轴流通风机设计中的适用性。 著录项

To control the separation of flow past an airfoil with a simple jet mechanism, based on the Large Eddy Simulation from Favre, a suction-blowing combined jet is studied with holes placed on a NACA0012 airfoil's upper surface and Re = 104 ... Z Zhang,T Wang,Y Wang,... - 《Journal of...
Numerical solution of 2D Euler equations for the transonic flow past over NACA0012 and RAE2822 airfoils using high order accurate Runge-Kutta Discontinuous... The Runge-Kutta Discontinuous Galerkin (RKDG) finite element method has the several advantages. First, the method is better suited than finit...
