FLUIDAPRO LIBRARY
The FLUIDAPRO library is designed to dynamically simulate fluid systems. Complex fluid systems where heat transfer is coupled with control could be easily evaluated with this library.
Features
The purpose of the FLUIDAPRO professional library is to model and study the transient simulation of fluid systems. The following are the most important features of the library:
- Gas, liquid and two-phase flow regimes for ideal or real fluids
- Reverse flow, inertia and high speed phenomena are considered in pipes, volumes and junctions
- Calculation of concentrated (valves) and distributed (pipes) pressure losses
- Heat transfer between walls (pipes and tanks) and the fluid
- Single tank models are available with the option of liquid level calculation
- Pneumatic/hydraulic actuators, check valves, 3- and 4-way controlled valves and pressure regulators
- Other special components such as heat exchangers and liquid pumps
Another phenomenon modelled in pipes, pumps or other components is the bubble formation due to the cavitation phenomena in a liquid. Besides, FLUIDAPRO facilitates the analysis of transient aspects due to inertia (pressure waves and water-hammer) and bubble collapse.
Using drag & drop methodology, the user can quickly create the fluid diagram to be analysed, the representation of which is very similar to the physical system. The FLUIDAPRO library provides a large palette of components to be inserted (click and drag) in a model. Other components that a user may possibly require can be easily built by means of inheritance and aggregation.
Thanks to EcosimPro’s features, libraries can be built that are easy to configure and extend, adding any components and characteristics as needed. This can be done graphically through a simple, user friendly interface, or through EcosimPro’s object-orientated language which makes it possible to re-use existing codes.
One of the library’s biggest advantages is the possibility of its use in the multidisciplinary facet of EcosimPro. This means that we can jointly study, for example, dynamic fluid systems together with heat transfer processes and control diagrams.
Components
From a computational point of view, components are divided into two classes:
- Capacitive elements (C), integrating the mass and the energy conservation equations
- Momentum elements (M), calculating explicitly the mass flows between capacitive elements
The FLUIDAPRO library has the following component types:
- Volumes, heat exchangers and tanks
- Pumps, pipes and tubes
- Junctions, valves, filters, vacuum pump
- Other topological components such as the tee component, electro-valves and actuators
Finally, the use of thermodynamic functions is another basic technique when using FLUIDAPRO components. Four categories of fluids are presented:
- Perfect gases
- Simplified liquids (energy and transport properties not depending on pressure)
- Van der Waals fluids
- Real fluids that consider all possible zones of operation (liquid, superheated, supercritical and two-phase flow)
