Abstract
Here we analyze a numerical model of a cubic lattice with linear elasticity and random heat sources on its upper and lower boundaries, consider methods which can be used for visualizing the kinetics of energy transfer and recording the history of events in such a system, and present some general results for its 2D and 3D cases. Also considered are the formation and propagation of localized energy states (“energy bundles”) and the rise of thermal resistance. It is shown that the thermal resistance at the interfaces of media with different parameters can be used for efficient heat removal and elimination of side effects in friction in a modified Prandtl–Tomlinson model with energy losses via substrate strain generation.
