Abstract
In this paper, Lees-Edwards periodic boundary condition is modified and successfully applied to form a stable high-shear-rate Couette flow. Thermal conductivity of liquid argon under shear flow is calculated with Green-Kubo formula by equilibrium molecular dynamics (EMD) simulation. The results show that the thermal conductivity is isotropic also in the presence of shear flow. In addition, the thermal conductivity in the flow direction does not vary with the shear rate and the constant value agrees well with the static thermal conductivity λ=0.132 Wm-1K-1.
