FluidDissipation for Applications - A Library for Modelling of Heat Transfer and Pressure Loss in Energy Systems

Abstract

The results of a free and open source MODELICA li- brary for convective heat transfer and pressure loss calculations of energy devices called FLUIDDISSIPA- TION will be presented based on the goals shown at the MODELICA Conference 2008 [1]. The FLUIDDISSI- PATION library is developed within the European re- search 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 pro- vide efficient and stable transient simulations. The library also provides convective heat transfer models and flowmodels ofmost heat transfer and pressure loss correlations using the also free and open source MOD- ELICA_FLUID library [2] as thermo-hydraulic frame- work for system simulation. Scope, implementation concept, numerical chal- lenges, verification and validation of the FLUIDDIS- SIPATION library will be exemplarily described (e.g. for convective heat transfer and pressure loss of two- phase flow). Industrial applications for thermo-hydraulic system simulation (e.g. air distribution circuit for supplemen- tal cooling, aircraft engine fuel feeding system) are presented using FLUIDDISSIPATION correlations im- plemented within MODELICA_FLUID models. A de- tailed documentation is available in the library itself.
