Webρ is the fluid density, p is the pressure, (x1, x2, x3) = (x, y, z) are the coordinates and (v1, v2, v3) are the corresponding components of the velocity vector v. The speed of sound squared a2 is equal to the derivative of the pressure p with respect to the density ρ, at constant entropy S: [6] As a result, the flow equations can be written as: WebAn integral part of fluid dynamics is vorticity. Heuristically, it measures the local rotation of a fluid parcel. For solid objects we do not speak of the vorticity of an object but instead we refer to its angular velocity. These two concepts are related but vorticity is more useful when discussing rotating objects that deform, as a fluid does. The vorticity of a given
WebMar 10, 2003 · The non-dimensional rotation rate, α (ratio of the surface speed and freestream speed), is varied between 0 and 5. The time integration of the flow equations is carried out for very large dimensionless time. Vortex shedding is observed for α < 1.91.
