Abstract

Thermodynamics and kinetics of nano-scale bubble formation in liquid metals such as Li and Pb were studied by molecular dynamics (MD) simulations at pressures typical for magnetic and inertial fusion. Two different approaches to bubble formation were developed. In one method, radial densities, pressures, surface tensions, and work functions of the cavities in supercooled liquid lithium were calculated and compared with the surface tension experimental data. The critical radius of a stable cavity in liquid lithium was found for the first time. In the second method, the cavities were created in the highly streched region of the liquid phase diagram; and then the stability boundary and the cavitation rates were calculated in liquid lead.The pressure dependences of cavitation frequencies were obtained over the temperature range 700-2700°K in liquid Pb. The results of MD calculations for cavitation rate were compared with estimates of classical nucleation theory.
