- Any intermediate solution can also be implemented (for example, simultaneous supply of a fluid to 3 sets of channels, for example 21, 22, 23 for a first pass, then the fluid collected at the outlet of these channels 21, 22, 23 is redistributed for a second pass at the input of channels 26, 25, 24 respectively; or the simultaneous supply of a fluid to 2 sets of channels, for three successive passes ).
- the channels have a rectangular, or round, or triangular cross section, etc. in the plane (X, Z).
