We use N-body simulations of a moderately coupled (coupling parameter γ = 0.11), classical, electron-proton plasma to investigate the electron heat flux in a steep temperature gradient. The thermal Knudsen number K3T is in the range 10-3≲ Ke,T ≲ 10-1. We show that under such circumstances the electron heat flux is approximately 3/4 of the canonical Spitzer & Härm value for Ke,T ≲ 5 10-2. For Ke,T ˜ 5 10-2 the non local contribution to the heat flux is no longer negligible and the heat flux saturates at roughly 10-1 times the free streaming value. The simulations are based on N-body techniques which are well suited for moderately coupled plasmas and allow for an accurate description of close and distant encounters, which both contribute to the transport properties in such plasmas.
