WebConcurrent and Countercurrent Exchange These models involve the exchange of a dissolved material from a high concentration solution to a low concentration solution where the solutions are separated by a permeable membrane. This type of exchange is very common in biological and industrial applications. 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 chemical, 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 a…
