Notes:
A self-similar model for the ablation driven by thermal radiation is developed for the case in which the ablated flow cannot freely expand and it is optically thick to the impinging radiation. The results show that the motion is governed by a dimensionless parameter, which determines the importance of the radiation heat conduction relative to the convective energy flux. The model can be applied to the situation arising in ion beam fusion targets, where a cold pusher is ablated by blackbody radiation emitted by the beam absorber layer that surrounds it and tamps the ablated flow. The scaling laws for the magnitudes of the flow are found and the main differences with free flow ablation are discussed.
