Information

Undirected implementation of the transport delay.

Delays the temperature and massFraction, not pressure, since pressure differences propagate with speed of sound, and since delaying only steady state pressure p not inertial pressure r might lead to undesirable behavior.

Note that this component uses the spatialDistribution operator, that has some artefacts (see Fig. 1) for high and low non-dimensional speeds v (possibly due to inerpolation or extrapolation of the function). Therefore minimum and maximum speed in the non-dimensional coordinate x (inlet @ x=0, outlet @ x=1) is limited. The default limits are [0.01, 50], so the delay is limited by default to [0.02s, 100s]. This limit can be adjusted in the advanced parameters tab.
