    Academic text (1997)
  • The gas-compression analogue would be to set up a counterflow heat exchanger to absorb heat from the hot-to-cold stream and give it back to the cold-to-hot stream.

Morphology

counterflow = counter + flow (transparent) = counter + flow

Clear compound of 'counter' (opposite/against) + 'flow'; the meaning directly follows from the components.

Etymology

The word counterflow joins counter- meaning 'against' and flow meaning 'movement'. So a counterflow is a movement that goes the other way to another flow, which is why the word describes two flows moving in opposite directions.
