Hybrid model for laser interaction with low-density foams
Original language description
We propose a novel hybrid model that describes laser-driven homogenization of individual foam elements as a competition between isothermal expansion (due to volumetric heating by electron heat flux) and surface ablation by the incident laser. The model is formulated in terms of ordinary differential equations for mass, momentum, and energy conservation and its parameters are chosen according to the detailed PIC simulations of laser-cylinder interaction. Cross-sections for laser absorption and scattering are calculated from the Mie theory for electromagnetic scattering on sub-wavelength cylindrical particles. The proposed micro-scale model is implemented in the PALE hydrodynamic code for laser-plasma interaction modeling. The capabilities of the hybrid model are demonstrated by successfully reproducing experimental data for several experiments at PALS facility.
