ABSTRACT
Thermal radiation redistribution inside a cylindrical hohlraum is discussed for uniform disc and two-ring sources. The flux conservation equation, coupled with self-similar scaling relation for the re-emitted flux, is solved to obtain the radiation temperature profile inside a gold capillary hohlraum at various times. The axial view factors required for the calculations are derived analytically in a closed form, which not only exactly reproduce the numerical results [G. D. Tsakiris, Phys. Fluids B 4, 992 (1992)] but also simplifies the overall problem enormously, both in terms of computational time and effort. © 2000 American Institute of Physics.
