Information

Version 1.1.0 of the DLR Thermofluid Stream Library.

• Updated graphical layout, both diagram and icon, of connectors Inlet and Outlet to be structured according to the convention of the Modelica Standard Library.
• Updated flow resistance model that now provides the ability to choose different shapes for cross sectional area and additional pressure loss functions collected in FlowResistance sub-package.
• Fixed bug in cross-flow heat exchanger: solution not converging for increasing number of discretization elements.
  • Scale reference mass-flow for heat transfer coefficient if stream is split into parallel streams.
  • Introduce parameter nCellsParallel for general usage in all discretized heat exchangers.
• Updated discretized and NTU heat exchangers to inherit from common base components.
  • Added summary record to NTU heat exchangers.
  • Changed direction of the ThermalConductor in cross-flow heat exchangers. This causes heat flow from A to B to be positive, similar to the counter-flow heat exchangers.
  • Corrected an error in the undirected counter-flow heat exchanger. Now m_flow_A and m_flow_B correspond to the flow through channel A and B respectively.
• Fixed bug in PartialVolumeM and PartialVolumeN: noEvent operator now works on mass-flow-related if-statements.
• Fixed wrong handling of conditional connectors by removing input binding for conditional connectors and enabling or disabling conditional connectors which depend on the setEnthalpy parameter.
