Computer simulation of ventilation start and stoppage

Author: J. Krawczyk

The paper presents computer calculations of flow transients in simple network ventilated by a three fan station.

Two mathematical models were compared: the simpler one assuming air incompressibility in which the network is described as a lumped constants system and the ID compressible flow model.

Combined characteristic of ventilation systems were applied to study the effects of inlet damper resistance on the character of transients.

The results are graphed to show time variations of flow rate and pressure at the selected points.
