Transverse Non-Uniformities in Steady-State Ablative Flow

摘要

Flow and pressure transverse perturbations in a hot inhomogeneous plasma are described by means of a steady-state analytical model in the context of laser-matter interaction. We show that perturbation coupling and adequate boundary conditions lead to results different from the thermal models. Comparison is done with irradiance smoothing experiments. A quite good agreement is obtained for large wavelenghts of the perturbations. For shorter wavelenghts, the treatment of time-dependent convective flows would be necessary. (ERA citation 11:055567)
