The results of a free and open source MODELICA library for convective heat transfer and pressure loss calculations of energy devices called FLUIDDISSIPATION will be presented based on the goals shown at the MODELICA Conference 2008. The FLUIDDISSIPATION library is developed within the European research project EuroSysLib.

The library delivers a broad range of verified and validated correlations describing convective heat transfer and pressure loss of fluids in energy devices. These correlations are numerically optimised to provide efficient and stable transient simulations. The library also provides convective heat transfer models and flow models of most heat transfer and pressure loss correlations using the also free and open source MODELICA_FLUID library as thermo-hydraulic framework for system simulation.

Scope; implementation concept; numerical challenges; verification and validation of the FLUIDDISSIPATION library will be exemplarily described (e.g. for convective heat transfer and pressure loss of twophase flow).

Industrial applications for thermo-hydraulic system simulation (e.g. air distribution circuit for supplemental cooling; aircraft engine fuel feeding system) are presented using FLUIDDISSIPATION correlations implemented within MODELICA_FLUID models. A detailed documentation is available in the library itself.
