FluidDissipation is a free and open Modelica Library for calculations of pressure differences and heat transfer. It is developed by XRG Simulation.

The library is open source and can be downloaded in the version 1.1.5 for Dymola and MSL 3.2.1.

List of revisions:

• Removed Integer modifications of enumeration parameters from Examples.
• Removed non-specified annotations (except Commands).
• Revised laminar and transition regime of dp_edgedOverall_MFLOW and dp_edgedOverall_DP. Please note, that the new model will calculate higher pressure drops in laminar and transient region.
• Removed a unit failure in verification models for flat and round tube heat exchangers.
