Numerical simulation of laser-produced plasma expansion on a droplet surface
Scientific Reports, 2023 AbstractIn this study, a numerical model of the plasma expansion on a droplet surface based on the initial plasma method was proposed. The initial plasma was obtained through the pressure inlet boundary condition, and the effect of ambient pressure on the initial plasma and adiabatic expansion of the plasma on the droplet surface, including the effect ...
