Incompressible flow high speed rail
Did you know?
WebWhen a fluid flow is compressible, the fluid density varies with its pressure. Compressible flows are usually high speed flows with Mach numbers greater than about 0.3. Examples include aerodynamic applications such as flow over a wing or aircraft nacelle as well as industrial applications such as flow through high-performance valves. WebA fluid is said to be incompressible when the mass density of a co-moving volume element does not change appreciably as the element moves through regions of varying pressure. In other words, for an incompressible fluid, the rate of change of following the motion is zero: that is, (1.76) In this case, the continuity equation ( 1.40) reduces to
