3. Usual charge-air line architectures
The following applies only to supercharged engines equipped with a charge gas cooling system.
3.1 A reminder about exchanger modeling
By definition, when we want to characterize a tube or pipe through which a fluid flows, we need to know :
the pressure drop across the pipe,
the thermal power exchanged.
In this type of stationary modeling, we consider the fluid flow to be constant. In this case, the pressure drop for a given flow cross-section is represented by :
