The first section considers the flow about a sphere. The second section considers the flow about the so-called Hill’s vortex. For both flows, the velocity field and stream functions are derived and the flow properties are studied. Both flows are excellent candidates for the ...
WebThe spherical coordinate system is aligned such that = 0 is in the ^z-direction. We seek to model a spherical vortex of radius aand propagation velocity Uz^, hence we nondimensionalize position as x= ax~, velocity as u= Uu~, and pressure as p= U2ˆp~, where tildes indicate nondimensional quantities. WebNov 10, 1998 · This is referred to as the compressible Hill's spherical vortex (CHSV). It corresponds to axisymmetric compressible Euler flow in which, within a vortical bubble, the azimuthal vorticity divided by the product of the density and the distance to the axis remains constant along streamlines, with irrotational flow outside the bubble.
