Counter and parallel flow heat exchanger
WebTo understand the heat flux distribution the temperature distributions on the outside wall of the water channel were visualized by an IR camera. As the results, it was shown that the difference in heat transfer rate between the parallel and counter flow was a little because of the large temperature difference in heat transfer.
