In counter flow heat exchangers
WebNov 1, 2024 · Counter-flow Arrangement: In the kind of counter-flow heat exchangers, unlike the arrangement of parallel-flow, the fluids enter at the opposite ends, move in the opposite directions, and leave at the opposite ends. Cross-flow: The fluids can also flow in perpendicular directions which is known as cross flow arrangement. The two main types … WebCountercurrent exchange and cocurrent exchange are two mechanisms used to transfer some property of a fluid from one flowing current of fluid to another across a barrier allowing one way flow of the property between them. The property transferred could be heat, concentration of a chemical substance, or other properties of the flow.
