Description: 问题考虑围绕翼型的流动在4°攻角和一个自由流马赫数0.8。流量是跨音速，并有近于上（吸气）侧中间弦m/c=0.45一个相当强烈的震撼。弦长为1米。-The problem considers the flow around an airfoil at an angle of attack and a free stream Mach number of ( ). The flow is transonic, and has a fairly strong shock near the mid-chord ( ) on the upper (suction) side. The chord length is 1 m.

Description: This paper considers geometric error control in the parabola-blending linear interpolation
method (Zhang, et al., 2011). Classical model of chord error by approximation with contact circle on the
parabolas leads to incorrect result. By computing the geometric error directly without accumulating the
approximation error and chord error, the authors realize correct geometric error control by establishing
inequality constraints on the accelerations of the motion.

Description: In this book , a low-speed airfoil over the NACA 0012 airfoil at 2° and 14° attack angles with
the given inlet velocity of 0.25 m/s, was modeled and computational fluid dynamic (CFD)
analysis were performed using FLUENT in ANSYS. The Reynolds number based on the chord is
roughly 𝑅 𝑒 = 2.88 × 106. The flow was modeled as incompressible and inviscid. All setup and
procedures were done by following the steps provided Cornel University website. Though, mesh
independence was achieved for 2° attack angle, for 14° attack angle which is more than the stall angle, mesh independence was not achieved. Lift and drag coefficient increases as the number of mesh element or the attack angle increases.-In this book , a low-speed airfoil over the NACA 0012 airfoil at 2° and 14° attack angles with

Description: shape of an image :
Shape factors are dimensionless quantities used in image analysis and microscopy that numerically describe the shape of a particle, independent of its size. Shape factors are calculated measured dimensions, such as diameter, chord lengths, area, perimeter, centroid, moments, etc.
