Title: Flow in a bundle of tubes in alternate rows

Description: 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.
