Analysis of heat conductivity in a 2D hard disk system
Abstract
Using numerical simulations, we study the heat conductivity in a 2d Hard Disk system. We find nonlinear temperature profiles for diferent gradients, and use this profiles to obtain the empirical expresion of heat conductivity κ(T,ρ). We compare our results with predictions based on the Enskog theory, finding good agreement even for large gradients. Also we find that Henderson state equation for Hard Disk stands for our system.
