Abstract

The laser ablated plasma flow and subsequent plasma density profile in steep plasma temperature gradient in spherical geometry are studied. Using local flux-limited model of heat flow the effect of flux-inhibition on the hydrodynamics of plasma ablation zone is investigated. The radial variation of thermal flux through local flux-limited model with recently accepted numerical range of flux-limit ≈ 10% of the free streaming is in close agreement with Spitzer's classical thermal conduction reduced by about an order of magnitude which may be attributed to the presence of megagauss level self-generated magnetic fields as predicted earlier to interpret experimental observations on X-rays emission spectra.
