Abstract

Abstract

The pulse shapes of loading pressure and driven laser were deduced based on compression isentrope of condensed matter, and the ramp compression simulations of aluminum were performed by hydrodynamic code MULTI. The process of the ramp compression is described with the following parameters: temperature, pressure, density, particle velocity and entropy production. Results show that the entropy production of the ramp compression process is small. This work can provide important supports for laser-driven ramp compression experiments in near future.
- quasi-isentropic compression,
- entropy production,
- compression wave,
- shaped laser
