VCL Version 2.14

Vapor Cycle Library 2.14 is part of Modelon's 2025.1 release. New versions of Modelon's libraries are sold and distributed directly from Modelon, as well as approved resellers.

Version 2.14 contains the changes described below.

New features

  • Extended Physics-based Solving (PbS) support for TwoPhaseTwoPhase.CounterFlow, TwoPhaseTwoPhase.CapillarySuctionLine, TwoPhaseAir.CrossFlow, Tanks.PhaseSeparator.
  • Added a new FourWayTwoPosition valve to support reversing heat pump cycle.

Improvements

  • Multiple improvements for robustness of performance of two-phase fluid simulations in MBL 4.6, in particular the pressure drop correlation by Friedel and evporation correlations.
  • Improved performance at very low flow rates when using the single-phase heat transfer correlation by Gnielinski.

Fixed issues

  • Added appropriate torque characteristics class in Pump model in place of the default base class.
  • Removed duplicate code for all components in FlowModifiers, they now extend from FlowModifiers in Modelon Base Library.
