Infinite Flow Resistance (2P)

Perfectly insulated break in two-phase fluid network


Two-Phase Fluid/Elements

  • Infinite Flow Resistance (2P) block


The Infinite Flow Resistance (2P) block represents a break in a two-phase fluid network. There is no mass or energy flow through the break. However, the fluid properties, specified by the Two-Phase Fluid Properties (2P) block connected to the circuit, are the same on both sides of the break. Use this block to set the priority and initial target value to the differences in pressure and specific internal energy between port A and port B.


To set the priority and initial target values for the block variables prior to simulation, use the Initial Targets section in the block dialog box or Property Inspector. For more information, see Set Priority and Initial Target for Block Variables.


The block has a pair of two-phase fluid conserving ports, A and B, representing branches of adjacent two-phase fluid networks.
