Word of the Week – Conduction

Word of the Week – Conduction

Conduction For geothermal applications, this refers to heat transfer in solids where thermal energy flows via microscopic-submicroscopic collisions of particles, which at a macro level is seen as solid-state diffusion. A vertical conductive thermal gradient is linear...

Word of the Week – Convection

Word of the Week – Convection

Convection Refers to heat transfer by fluid circulation in permeable rocks where thermal energy is transported with the flow of hot fluid (water or steam).

Word of the Week – Cooling Tower

Word of the Week – Cooling Tower

Cooling Tower Plant equipment that is used to dissipate heat into air rather than into a river. Cooling is induced in two different ways. For binary plants, dry cooling towers use fans to draw air across a heat exchanger and this removes heat from a working fluid...
