The correct global local node mapping for the quadraticelement mesh in the figure is

When is a flow compressible? compressible flow differs from an incompressible one in that significant change happens in the density

Boundary layer(边界层) Although frictional effects in slightly viscous fluid are indeed present, they are confined to a thin layer near the surface of the body, and the rest of the flow can be considered inviscid. (1904, Prandt/)

Properties of Pressure Vertical to the surface and point into it. At any point, pressure is independent of orientation

Chapter 1 Introduction 1.1 Preliminary Remarks When you think about it, almost everything on this planet either is a fluid or moves within or near a fluid. -Frank M. White What is a fluid?

Chapter 4 Incompressible Flow Over Airfoils Of the many problems now engaging attention, the following are considered of immediate importance and will be considered by the committee as rapidly as funds can be secured for the purpose... The evolution of the more efficient

11. 4 PRANDTL-GLAUERT COMPRESSIBILITY CORRECTION The methods that approximately take into account of the effects of compressibility by correct the Incompressible flow results Is called compressible corrections

This chapter mainly deal with the properties of two-dimensional airfoils at mach number above 0.3 but below 1, where the compressibil ity must be considered

本节要点只有 一、计算通过正激波的流动特性变化

一、可压缩流动的基本特征: x The pivotal aspect of high -speed flow is that the density is avariable一一密度是变量
