Heat waves driven by thermal radiation in tamped flows
The heating of matter driven by thermal radiation is studied by means of a simple model, under conditions where the material cannot freely expand. Supersonic and ablative regimes are identified when the radiation field is not in local thermodynamic equilibrium with the matter and, in a later phase,...

| Sumario: | The heating of matter driven by thermal radiation is studied by means of a simple model, under conditions where the material cannot freely expand. Supersonic and ablative regimes are identified when the radiation field is not in local thermodynamic equilibrium with the matter and, in a later phase, when equilibrium is reached. The scaling laws characterizing the magnitudes of the heated material are found for the different regimes. Application to an ion-beam-fusion target is examined and the effect of an active tamper that pushes the ablated material is analyzed. © 1992 The American Physical Society. |
