9.1 Normal Shock Waves Shock waves are large-amplitude waves that travel in a gas. They emanate from the wings of a supersonic aircraft, from a large explosion, from a jet engine, and ahead of the projectile in a gun barrel. They can be oblique waves or normal waves. First, we will consider the normal shock […]

Compressible Flows: Basics, Speed of Sound and Isentropic Nozzle Flow
Compressible Flows Compressible flows occur when the density changes are significant between two points on a streamline. Not all gas flows are compressible flows, only those that have significant density changes. Flow around automobiles, in hurricanes, around aircraft during landing and takeoff, and around buildings are a few examples of incompressible flows in which the […]

External Flows : Potential Flow and Boundary-Layer Flow
8.1 Potential Flow BASICS When a body is moving in an otherwise stationary fluid, there is no vorticity present in the undisturbed fluid. To create a steady flow, a uniform flow with the body’s velocity is superimposed on the flow field so that the vorticitfree flow moves by the stationary body, as in a wind […]

External Flows : Basics , Flow Around Blunt Bodies and Flow Around Airfoils
External Flows The subject of external flows involves both low Reynolds-number flows and high Reynolds-number flows. Low Reynolds-number flows are not of interest in most engineering applications and will not be considered; flow around spray droplets, river sediment, filaments, and red blood cells would be examples that are left to the specialists. High Reynolds-number flows, […]
