Heat Transfer - an overview | ScienceDirect Topics

An HTF is a fluid or gas that has the ability to transport heat. In a CRS system, an HTF is used, on the one hand, to cool the absorber and, on the other hand, for the transport of the absorbed heat. Criteria for choosing an HTF are heat capacity, thermal conductivity, reached outlet temperature, and heat flux density.

Heat Transfer | Mantle Plumes and heat flow | Thermo-Chemical Mantle …

The term convection is often used to describe heat transfer that occurs between an object and a fluid flowing across it. Convection is, in essence, a type of conduction. In convection heat is transported mostly by the movement of material, rather than by conduction. Convection in the Earth''s mantle is the transport of heat by motion of the mantle.
