FLOW IN A BUNDLE OF TUBES IN ALTERNATE ROWS
Example of an internal flow whose organization plays a major part in the efficiency of a heat exchanger.
The tests emphasised the configurations (distance between rows, alternate positioning) that ensure all
elements of the bundle with a good distribution of clean flow and a reduction of their wake.
