Abstract

The paper presents the description of numerical modelling of heat transfer proceeding in metals in nano scale. The mathematical model of the problem analyzed is based on the interval coupled lattice Boltzmann equations for electrons and phonons supplemented by the boundary-initial conditions. The first, second and periodic type boundary conditions have been assumed. In this model, the standard two-dimensional 9-speed lattice (D2Q9) is used. The main concept behind this work was to use the directed interval arithmetic to analyze the thermal processes with the uncertain parameters. Moreover the periodic boundary conditions have been introduced to deal with the situation where heat transport takes place in a region with a large ratio of the length to the width. In the final part of the paper the numerical examples of two- dimensional heat transfer analysis are shown.
