PASSAGE®/SYSFLOW

 

Overview

  • PASSAGE®/SYSFLOW is a one dimensional (1D) computational fluid dynamics software for the prediction of flow network performance and system design and analysis.
  • PASSAGE®/SYSFLOW provides very useful information in understanding the flow splits in branched flow passages and the overall heat fluxes between components.
  • Using 1D  computational fluid flow software  is a very efficient and a relatively inexpensive tool for system analysis and design.
  • PASSAGE/SYSFLOW program is fast, user-friendly and effectively predicts performance in a variety of user-defined networks.
  • Steady state, compressible and incompressible flow network problems can be solved including heat transfer effects.
  • Virtually any flow network system and/or sub-system can be modeled using combinations of components included in the standard library.
  • A numerical model such as  PASSAGE/SYSFLOW fluid flow program as a design and analysis tool serves as an invaluable tool to study the flow and heat-transfer in complex systems and to optimize the design process in a more cost effective and timely fashion.

 

Features:

  • An X-Windows based graphical User Interface provides a user-friendly environment to build networks by interactively adding various components.
  • Existing components and their associated properties can be modified, deleted and moved easily to change the network characteristics or to build new networks from existing ones.
  • The Post-Processor is a powerful graphical tool for the result interpretation of pressure, velocity, temperature and density.
  •  Components:
    • Sources - fixed pressure or flows, pumps, fans
    • Pipes - different geometries
    • Fittings - contractions, expansions, bends, & junctions
    • Valves - proportional, relief
    • Heat Exchangers
    • Filters

Advantages of using Passage 3D FLOW with 1D SYSFLOW

Simultaneous use of PASSAGE: 3D FLOW and 1D SYSFLOW software provides a practical tool for solving complex flow and heat transfer problems. This capability allows modeling of complex systems followed by detailed analysis of sub-systems and components. Design process start with developing the overall concept, detailing its components and ensuring that the overall performance and efficiency targets are met. Using PASSAGE: SYSFLOW one can develop an initial concept, perform sensitivity analysis to determine its critical components and set directions and further development. One can then proceed with detailed design using PASSAGE: FLOW at the same time refining SYSFLOW models and testing prototypes.
