Pressure differential across tube or channel due to change in fluid velocity
The Fluid Inertia block models pressure differential, due to change in fluid velocity, across a fluid passage of constant cross-sectional area. The pressure differential is determined according to the following equation:
Use this block in various pipe or channel models that require fluid inertia to be accounted for.
The block positive direction is from port A to port B. This means that the flow rate is positive if it flows from A to B.
Fluid passage cross-sectional area. The default value is 8e-5 m^2.
Length of the fluid passage. The default value is 1 m.
Initial flow rate through the passage. This parameter specifies the initial condition for use in computing the block's initial state at the beginning of a simulation run. For more information, see Initial Conditions Computation. The default value is 0.
Parameter determined by the type of working fluid:
