Ab initio determination of thermal conductivity of CH in ICF regime
Abstract
Among the numerous parameters that condition the success of future inertial confinement fusion (ICF) experiments, electronic thermal conductivity plays a central role. Ab initio molecular dynamics is used to compute the thermal and electrical conductivities of CH in thermodynamical conditions relevant to Inertial Confinment Fusion. The ionic structure is obtained using molecular dynamics simulations based on an orbital-free treatment for the electrons. The transport properties were computed using ab initio simulation in the DFT/LDA approximation. The thermal and electrical conductivities are evaluated using Kubo-Greenwood formulation. These calculations are then used to check various analytical models widely used in hydrodynamics simulations of ICF capsule implosions. A perticular attention is paid to mixture laws.
