Confusion in heat ex-changer results interpretation

misterdd · February 12, 2013, 10:38

Hello everybody,
We have simulated a small portion of a heat ex-changer. Consider actual model consists of 4 X 4 X 6 units. We have initially simulated only a single unit and monitored temperature rise and pressure drop across its inlet and outlet. The results of first unit are used as an input parameter for the inlet of next unit. Repetition of the same led us to get the results at the outlet of 6th unit, i.e., we have pressure drop and temperature rise in complete one dimension.
If we see our whole system, our simulated units have a 16 (4 X 4) times repetition. How should we interpret the results for the whole system?

can we simply multiply the pressure drop 16 (4 X 4) times to get the pressure drop for the whole system??
