omnidirectional flux


ECSS-E-ST-10-04C Rev.1


scalar integral of the flux over all directions


  • NOTE This implies that no consideration is taken of the directional distribution of the particles which can be non-isotropic. The flux at a point is the number of particles crossing a sphere of unit cross-sectional surface area (i.e. of radius 1/√π). An omnidirectional flux is not to be confused with an isotropic flux.
