Comoving-frame radiation transport for nonrelativistic fluid velocities Academic Article uri icon

abstract

  • We investigate the comoving-frame treatment of radiation transport for use in problems of nonrelativistic radiation hydrodynamics. The transport equation is re-derived, to O(v/c), retaining a term that is traditionally omitted. This reduced equation is not just formally, but also physically, correct to O(v/c), inasmuch as it keeps the wave speed bounded by light speed and can transformed to the correct Eulerian-frame transport equation in any physical regime. We strongly recommend that this equation, and its moments, be used in all situations where the fluid-flow speeds are nonrelativistic. 2001 Elsevier Science Ltd. All rights reserved.
