Powerful & Intuitive Modeling, Simulation & Optimization Tools
Engineering Simulation Solutions
Flownex® is a thermo-fluid simulations software package used in the industry to predict, design and optimise flow rates, temperatures and heat transfer in fluid systems.
Flownex Simulation Environment can aid in helping students to better understand and learn fundamental concepts in thermodynamic, heat-transfer, system-analysis and turbo-machinery related courses.
Flownex® SE determines pressure drop [ﬂow] and heat transfer [temperature] for the connected components of a complete system in steady state and transient, e.g. pumps or compressors, pipes, valves, tanks and heat exchangers.
Flownex Simulation Environment delivers technology that enables you to study how systems will behave in the real world, where fluid is the driving factor. Flownex system simulation relays the overall effect of changing specific properties on components, allowing clients to extensively examine all possible variations of a system in the design and optimization of systems.
Flownex core modules include all modules that form the core simulation function of Flownex SE.
FLOWNEX Basic Thermal Fluid Models
This is the basic Flownex steady state version. This conﬁguration includes the ability to deal with both liquids and gasses, the ability to deal with adiabatic ﬂows, as well as ﬂows with heat transfer. The network component models included in the standard version are reservoirs, pipes, ducts, pumps, fans, compressors, turbines, heat exchangers, valves and oriﬁces. This conﬁguration also includes visualization graphs, text outputs, result layers, data logger and result export to Excel, buttons, gauges, sliders, etc. of visualization is included as well as the ability to create compound components.
Advanced fluid thermal module
This conﬁguration includes advanced features such as gas mixtures, homogeneous two phase ﬂow, coupled heat transfer through solid structures, special components used in the design of turbomachinery such as rotating pipes and annulus. It also includes combustion modeling, the Script element and the Excel component.
Design and analysis module
This conﬁguration includes advanced features such as the designer routine, stochastic routines used in probabilistic analyzes (Sensitivity Analysis, Parametric Study). This capability can be applied to all libraries and on both steady state and transient modules.
The dynamic (transient) simulation features of Flownex include the following: The ability to start the simulation from steady-state or speciﬁed initial conditions; Variable time-step sizes; Open loop events can be speciﬁed at diﬀerent time steps (e.g. Varying or ﬁxing of variables; Switching controllers on or oﬀ; etc.) and the plot values of multiple parameters are displayed on the screen.
Nuclear models such as the Pebble bed reactor (Generation 2) and advanced pebble bed models (Generation 3). Includes link to RELAP allowing Flownex to communicate and run co-simulations with RELAP.
Flownex library modules include all modules that include integrated libraries in Flownex SE.
Control library conﬁguration includes analog components (controllers, Filters, Inputs and outputs IO, math functions and switches ), digital components (Counters, IO's, Logic, Switches and Timers) and some converters (analog to digital, digital to analog, integer to double, etc.). The Flownex OPC client is used to set up communication of Flownex inputs and results to and from tags in an OPC server.
Electrical library conﬁguration includes admittance components (generators, motors, transformers, etc.), auxiliary components (base power, base voltage, synchronizer, etc.), nodes (bus, ﬁxed voltage node, inﬁnite grid, etc.) and switches such as a breaker.
User extendibility allows users to write their own libraries consisting of components, editors, links, solvers, etc. that interface seamlessly with Flownex Simulation Environment. These user extendable libraries can then interact with existing or future Flownex Simulation Environment libraries such as the transient, design and analysis modules.
The Flownex SE automation (API) Application Programming Interface provides the functionality to integrate and automate Flownex SE from most existing Windows applications, e.g. Word, Excel, etc. Any application that allows scripting of Component Object Model (COM), Distributed Component Object Model (DCOM) or ActiveX components can now integrate with Flownex SE. The API is also accessible to any .Net aware application. The API module includes an integration to Simulink (Math Works). and includes existing links to other software like EES, MATHCAD and ANSYS enabling the ability to communicate and run co-simulations.
