HXL Version 2.14

Heat Exchanger 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

• A GasMultiDisplaySensor is added to HeatExchanger.Sensors.Lumped

Improvements

• The flow resistance correlation for two-phase flow in offset strip fin heat exchangers has improved robustness at zero or low flow rates, as well as at the phase boundary. This has been achieved by introducing a regularization interval for low Reynolds numbers (by default from Re = 4000, this can be changed by a correlation parameter) and by avoiding to evaluate expressions outside the range of vapor quality values that the correlation has been developed for. The correlated range is vapor quality from 0.2 to 0.8. At higher or lower values, the two-phase multiplier is kept constant.
• Description strings of media packages are improved for better usability
• Multidisplay sensors and visualizers are added to the test benches in HeatExchangers.CrossFlowAir

Bug fixes

• Corrected an issue in flat tube heat exchangers that geometric parameter set at the internal "geometry" instance (lower case g) did not take precedence over values set in the main input field "Geometry" (upper case G).
