the rate of transport of particles through a boundary


  • NOTE In contrast to flux, current is dependent on the direction in which the particle crosses the boundary (it is a vector integral). An isotropic omnidirectional flux, f, incident on a plane gives rise to a current of ¼ f normally in each direction across the plane. Current is often used in the discussion of radiation transport.
