On the wave theory in heat conduction
Web1 de jun. de 2009 · The conservation equations for heat conduction are established based on the concept of thermal mass. We obtain a general heat conduction law which takes into account the spatial and temporal inertia of thermal mass. The general law introduces a damped thermal wave equation. It reduces to the well-known CV model when the spatial … WebConduction occurs in solids. Metals are good conductors. Non-metals and gases are usually poor conductors. Poor conductors are called insulators. Heat energy is conducted from the hot end of an ...

Webwhere electromagnetic waves penetrate only minimally into a good conductor. In addition, thermal waves are strongly dispersive. Their phase velocity is directly dependent on the modulation frequency of the heat source. Therefore, it is not possible to produce propagating wave packets, since each partial wave propagates at its own phase velocity. 2.
