HXL Version 3.0

Heat Exchanger Library 2.14 is part of Modelon's May 2025 release. New versions of Modelon's libraries are sold and distributed directly from Modelon, as well as approved resellers.

Version 3.0 contains the changes described below.

Improvements

  • For two-phase fluid heat transfer, the ConstantCoefficient and TwoConstantCoefficients options have been removed. Instead a CoefficientsPerPhase option is added, which allow giving separate coefficients for the liquid, two-phase and vapor regions. ConstantCoefficient can be reproduced by giving the same values to all three regions, and TwoConstantCoefficients can be reproduced by giving identical values to the liquid and vapor regions.
  • The SinglePhase heat transfer correlation (predictive in single phase regions, inaccurate in two-phase region) has been removed. As replacement it is advised to use the SimpleTwoPhase correlation. This is identical in the single phase regions, and takes a user-defined heat transfer coefficient in the two-phase region.
  • Enhanced Parameter GUI for the FinTube heat exchanger. Parameter dependencies are now internally referenced, improving clarity and ease of configuration.
