User:Butakun/Taylor-Maccoll equation

From Wikipedia, the free encyclopedia

In fluid dynamics, Taylor-Maccoll equation is the governing equation for supersonic conical flow, written as


\left(1 - \frac{v^2}{a^2}\right) \frac{d^2 u}{d\theta^2}
  + \cot\theta\frac{du}{d\theta}
  + \left(2 - \frac{v^2}{a^2}\right) u
  = 0

v = \frac{du}{d\theta}

where

  • u is the velocity component in \hat{e}_r.
  • v is the velocity component in \hat{e}_{\theta}.
  • a is the speed of sound.
  • θ is the semivertex angle.
