Kovásznay modes in stability of self-similar ablation flows of ICF
Exact self-similar solutions of gas dynamics equations with nonlinear heat conduction for semi-infinite slabs of perfect gases are used for studying the stability of ablative flows in inertial confinement fusion. Both the similarity solutions and their linear perturbations are numerically computed with a dynamical multidomain Chebyshev pseudo-spectral method. Laserimprint results, showing that maximum amplification occurs for a laser-intensity modulation of zero transverse wavenumber have thusdoi:10.1209/0295-5075/84/25001 fatcat:ilcb5ibsgnhvzbjyjkivhuvasm
