Electrical analogy in heat transfer
WebHeat transfer theory. Maurice Stewart, in Surface Production Operations, 2024. 9.10.3 Radiation. Radiation heat transfer is a process where heat waves are emitted that may be absorbed, reflected, or transmitted through a colder body. Sun heats the earth by electromagnetic waves. Hot bodies emit heat waves. Most upstream oil- and gas …

WebA typical example of mass transfer is the immediate spread of a room freshener in an air-conditioned room. Convective mass transfer closely resembles convective heat transfer. The analogy between mass transfer and heat transfer is especially true for low concentrations of the species in the fluid and low mass transfer rates of the species.
