... cooling. The present work focuses on the design and testing of a small-scale prototype heat exchanger, for such a cooling system. Various prototypes of the heat exchanger were tested in a 1/10 th -scaled model of a section of the creek. A staggered, tube-bundle heat exchanger was used. The prototypes...
