Non-linear calculations of transient thermal conduction in composite materials

Using the recently formulated Lattice Monte Carlo method this work addresses transient thermal response in composite materials. Lattice-based random walks of virtual thermal energy particles are used to obtain temperature profiles in homogeneous and simple two-phase composites and compared to finite...
