The generation and decay of vorticity

摘要: Abstract Vorticity, although not the primary variable of fluid dynamics, is an important derived playing both mathematical and physical roles in solution understanding problems. The following treatment discusses generation vorticity at rigid boundaries its subsequent decay. It intended to provide a consistent very broadly applicable framework within which wide range questions can be answered explicitly. rate shown relative tangential acceleration boundary without taking viscosity into account generating mechanism therefore involves pressure gradient external only. inviscid nature independent no-slip condition boundary, viscous diffusion acts immediately after spread outward from boundaries. Vorticity diffuses neither out nor them, only...
