ducers are used <strong>to</strong> record pressures corre‐<br />
sponding <strong>to</strong> the N segments, and a mass flow<br />
meter is used <strong>to</strong> record air mass flow rate under<br />
the steady state condition. All these recorded<br />
values are then used as the system initial condi‐<br />
tions for the simulation. The transient pressure<br />
