Comparison between two models of nonlocal heat flux in laser‐generated plasma

摘要

Two models of nonlocal heat flux in laser‐driven plasmas have been presented by Luciani and Mora, and by Albrittonetal. The disagreement between them is shown to be only apparent: when used in exactly the same conditions, they actually give the same answer, provided that the correct tabulated propagator is used in the integral giving the flux. A steepening of the temperature profile at critical density still exists for both models.
