Heat Transfer Principles
Heat transfer is the movement of thermal energy from one object or region to another. It is a fundamental process in many natural and industrial systems, including the operation of power plants, the cooling of electronic devices, and the transfer of heat from the sun to the earth.
There are three main mechanisms of heat transfer: conduction, convection, and radiation.
Conduction
Conduction is the transfer of heat through direct contact between objects or materials. When two objects are in thermal contact, the hotter object will transfer heat to the cooler object until they reach the same temperature. The rate of heat transfer by conduction is proportional to the temperature difference between the objects, the surface area in contact, and the thermal conductivity of the materials.
Convection
Convection is the transfer of heat by the movement of a fluid (liquid or gas). When a fluid is heated, it becomes less dense and rises, while cooler fluid takes its place. This creates a convection current, which can transfer heat from one part of a fluid to another.
The rate of heat transfer by convection is proportional to the temperature difference between the fluid and the surrounding environment, the surface area of the fluid, and the velocity of the fluid.
Radiation
Radiation is the transfer of heat through electromagnetic waves. All objects emit thermal radiation, which is a form of electromagnetic radiation. The rate of heat transfer by radiation is proportional to the temperature of the object, the surface area of the object, and the emissivity of the object.
