Convection, Conduction & Radiation

Convection, Conduction & Radiation 1 Convection, Conduction & Radiation There are three basic ways in which heat is transferred: convection, conduction and radiation. In gases and liquids, heat is usually transferred by convection, in which the motion of the gas or liquid itself carries heat from one place to another.

Chapter 15: Radiation Heat Transfer

Radiation differs from Conduction and Convection heat t transfer mechanisms, in the sense that it does not require the presence of a material medium to occur. Energy transfer by radiation occurs at the speed of light and suffers no attenuation in vacuum. Radiation can occur between two bodies separated by a medium colder than both bodies.

(4) Radiation: exchanging heat with space (5) Latent heating: changing the phase of water Without adding (removing) heat to (from) the air parcel (1) Adiabatic Process: Expanding and compressing air ESS55 Prof. Jin-Yi Yu Conduction Conduction is the process of heat transfer from molecule to molecule. This energy transfer process requires contact.

of 19th century, experimental investigations on conduction of electricity (electric discharge) through gases at low pressure in a discharge tube led to many historic discoveries. The discovery of X-rays by Roentgen in 1895, and of electron by J. J. Thomson in 1897, were important milestones in the understanding of atomic structure.
