Abstract

The spatial and temporal evolutions of nonlocal heat transport in laser-produced aluminum plasmas are studied with the improvements of the Thomson scattering experiments and the kinetic Fokker-Planck simulations. The results are compared with the hydrodynamic simulations with the classical Spitzer-Härm theory. When another heater beam is used, the electron temperature decreases slowly and the temperature gradient becomes steep in the conduction zone. The nonlocal heat flux can be sustained at a high value with slow decrease for long time. The Fokker-Planck simulations considering electron-electron collisions can well describe the nonlocal heat transport process in laser-produced plasmas.
