Coefficient of pressure at stagnation point
http://www-mdp.eng.cam.ac.uk/web/library/enginfo/aerothermal_dvd_only/aero/fprops/poten/node37.html On a streamlined body fully immersed in a potential flow, there are two stagnation points—one near the leading edge and one near the trailing edge. On a body with a sharp point such as the trailing edge of a wing, the Kutta condition specifies that a stagnation point is located at that point. The streamline at a … See more In fluid dynamics, a stagnation point is a point in a flow field where the local velocity of the fluid is zero. A plentiful, albeit surprising, example of such points seem to appear in all but the most extreme cases of fluid dynamics in … See more • Stagnation point flow See more

Using Bernoulli's equation, the pressure coefficient can be further simplified for potential flows (inviscid, and steady): where u is the flow speed at the point at which pressure coefficient is being evaluated, and Ma is the Mach number: the flow speed is negligible in comparison with the speed of sound. For a case of an incompressible but viscous fluid, this represents the profile pressure coefficient, since it is … WebStagnation Pressure. The Bernoulli Equation states that the energy along a streamline is constant - and can be modified to. p1 + 1/2 ρ v12 + γ h1. = p2 + 1/2 ρ v22 + γ h2. = …
WebFeb 28, 2008 · Why the pressure coefficient is greater than one. I am using simpleFoam to solve a steady incompressible low speed flow. It is similar to cylinder flow. The air speed is about 27.5 m/s. However, the Cp I got at the stagnation point is slightly greater than 1 (between 1 and 1.08). We knew that Cp should be less than 1 for the incompressible flow.
