Description

Add-On Required: This feature requires the Simscape Acoustics add-on.

The Controlled Volume Velocity Source block represents an ideal volume velocity source that is powerful enough to maintain the specified volume velocity through it regardless of the pressure across the source.

The output volume velocity is U=uT, where uT is the numerical value presented at the physical signal port.

The arrow indicates the positive direction of the volume velocity flow.
