Hurwitz's theorem (composition algebras)

Hartmann number (Ha) is the ratio of electromagnetic force to the viscous force first introduced by Hartmann. It is defined by:

$\mathrm{H}\mathrm{a}=BL\sqrt{\frac{\sigma }{\mu }}$

where

• B is the magnetic field
• L is the characteristic length scale
• σ is the electrical conductivity
• μ is the dynamic viscosity
