Domains: Continuous. Size: 1-D. Kind: Iconic Diagrams (Hydraulics).
This model describes the laminar flow through a component:
pa.phi = pb.phi = G*(pa.p - pb.p);
The variable conductance G is given by an input signal. The pressure at both ports has a lower limit that is equal to the vapour pressure. Therefore the actual equations used in this component are:
p1_lim = if pa.p < p_vapour then p_vapour else pa.p end;
p2_lim = if pb.p < p_vapour then p_vapour else pb.p end;
dp = p1_lim - p2_lim;
pa.phi = G*dp;
pb.phi = pa.phi;
There is no check on the validity of laminar flow in this component!
