Description
Add-On Required: This feature requires the Simscape Acoustics add-on.
The Acoustic Resistance block models a linear resistor using the equation
where:
P is pressure.
U is the volume velocity.
R is resistance.
The conserving acoustic ports + and - correspond to the positive and negative terminals of the block, respectively. The volume velocity is positive if it flows from positive to negative. The pressure across the block is equal to the difference between the pressure at the positive and the negative terminal, P(+) – P(-).
