Abstract

Pressure pulsations appear on solid surfaces during the interaction of laser pulses. We use a computer to obtain solutions to the 2D Navier-Stokes equations, representing axisymmetric unsteady jet modeling an erosive plume. We analyze the gas dynamics only, without looking after ionization processes, boiling, and so on. Significant pressure pulsations arise, depending on irradiation conditions and properties of the irradiated substances, and we discuss them in comparison with experimental data.
