Short Description

Based on 10 years of LMS-Imagine’s experience in hydraulic system modelling, a library to model hydraulic systems has been developed. It is a Thermal-Hydraulic library with calls to media properties. It is constituted of elementary thermal-hydraulics components.

Long Description

The standard LMS-Imagine Thermal-Hydraulic library (C-coded) has been partially re-developed in modelica. The added-value of modelica has been investigated for Thermal-Hydraulic applications.

• Development of some thermal-hydraulic modelica library components in the AMESim environment.

• Work on the acausal approach for fluid networks as CC, RR.

• The review of the different components (types, complexity, …) has been done. Utilities have been reviewed (flow equations, …) to evaluate the way the models should be implemented with modelica.

• Calls to AMESim Fluid properties are used for iso-model comparison between AMESim C-coded/Modelica approaches. It allows using Application-oriented fluids database.

• Checks that the existing functionalities of AMESim still work with Modelica components (linear analysis, cpu-time with Run Stats, …)
