Version 2 7

Liquid Cooling Library 2.7 is part of Modelon's 2021.2 release. New versions of Modelon libraries are sold and distributed directly from Modelon, as well as approved resellers.

Build 1 (2021-06-10)

Version 2.7 is updated for use with Modelon Base Library 3.7.

New features

  • A new split component was added, that allows direct specification of flow rate per path.
  • Added derivatives in Media base class and updated the derivative annotation, so that tools can generate analytic Jacobians.

The following media are added:

  • Hydraulic oil MIL-83282
  • Coolant MIL-87252
  • Lubricating oil MIL-23699
  • Lubricating oil Mobil Jet Oil II, a variant of MIL-23699.

The following HeatExchanger models are added:

  • HeatExchangerTest_TableBasedQ - The rate of heat transfer is mapped directly from the mass flow rates of both media via a look-up table using linear interpolation.
  • Gas-Gas StaticEffectivenessTableFromQ Heat Exchanger
  • Liquid-Gas StaticEffectivenessTableFromQ Heat Exchanger
  • Liquid-Liquid StaticEffectivenessTableFromQ Heat Exchanger


  • The following flow resistance models have been updated to account for bidirectional flow:
    • LiquidCooling.FlowResistances.Geometric.Contraction
    • LiquidCooling.FlowResistances.Geometric.AbruptContraction
    • LiquidCooling.FlowResistances.Geometric.Expansion
    • LiquidCooling.FlowResistances.Geometric.AbruptExpansion
    • LiquidCooling.FlowResistances.Geometric.FlushMountedIntake
  • Fixed minor bug in EpsNTU heat exchangers to use the counterFlowEps as a default calculation of effectiveness
