Cocurrent and countercurrent exchange mechanismsThe magnitude of the property to be exchanged, is represented by shading. The direction of transfer across the barrier is from the greater to the lesser magnitude..

Cocurrent and Countercurrent heat exchange

Countercurrent exchange is a mechanism occurring in nature and mimicked in industry and engineering, in which there is a crossover of some property, usually heat or some component, between two flowing bodies flowing in opposite directions to each other. The flowing bodies can be liquids, gases, or even solid powders, or any combination of those. For example, in a distillation column, the vapors bubble up through the downward flowing liquid while exchanging both heat and mass.
