title: Heat transfer text: Heat transfer Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes. Engineers also consider the transfer of mass of differing chemical species, either cold or hot, to achieve heat transfer. While these mechanisms have distinct characteristics, they often occur simultaneously in the same system. Heat conduction, also called diffusion, is the direct microscopic exchange of kinetic energy of particles through the boundary between two title: Heat transfer text: the generation, use, conversion, and exchange of heat transfer. As such, heat transfer is involved in almost every sector of the economy. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes. The fundamental modes of heat transfer are: By transferring matter, energy—including thermal energy—is moved by the physical transfer of a hot or cold object from one place to another. This can be as simple as placing hot water in a bottle and heating a bed, or the movement of an iceberg in changing ocean currents. A title: Heat Transfer with Thermal Waves and Thermal Resonance text: Heat Transfer with Thermal Waves and Thermal Resonance Thermal waves/resonance is the one of four basic heat-transfer modes. Unlike the other three modes (heat conduction, heat convection and heat radiation) that transport heat always from high temperature to low temperature with temperature gradient as the driving force, this mode of heat transfer comes from cross-coupling among different transport processes in the medium and can transport heat isothermally or even from low temperature to high temperature. This mode of heat transfer is characterized by its wave-type distributions of temperature or its various spatial/temporal derivatives depending on and tunable by the cross title: Heat transfer text: includes technologies for collecting and storing energy for later use. It may be employed to balance energy demand between day and nighttime. The thermal reservoir may be maintained at a temperature above or below that of the ambient environment. Applications include space heating, domestic or process hot water systems, or generating electricity.
