STREAMLINES FLUID FLOW IN NETWORKS.

MSDOS (will run in an MSDOS window [click here for MSDOS NOTES] under Windows).

STREAMLINES models the steady-state flow of homogeneous Newtonian fluids in pipes, ducts, loops, trees, and networks. It provides accurate, comprehensive, and well-documented analyses of duct and pipe sizing, fan and pumping power, pressure and flow control, and general system performance. STREAMLINES is particularly applicable to situations in which temperatures, densities, viscosities, and flow regimes varying throughout the system (as in chemical processes). Analysis can be either design or performance oriented.

Applications include: gas turbine inlet and exhaust ductwork; wind and water tunnel circuits; air and water building service; HVAC; process piping; boiler forced and induced draft; fire protection systems; gas and oil pipelines.

Capabilities/Features:

o Up to 100 nodes and streams (links).

o Design or performance models.

o Handles air, water, liquids, gases, or saturated and superheated stream.

o Density, viscosity, and vapor pressure calculated for air, water, and steam. You can create property data files for other materials.

o Darcy-Weisbach, Hazen-Williams, Isothermal, or Weymouth solutions.

o Laminar, critical, transition, and fully turbulent flow regimes.

o English or SI units (and HVAC water column forms).

o Static or total pressure basis.

o Varying temperatures, densities, viscosities, and vapor pressures allowed.

o Handles circular, rectangular (HVAC), and irregular conduit crossections.

o Can specify external supply and demand flows.

o Open or closed links.

o Multiple parallel links (e.g., steam surface condensers, fire sprinkler systems).

o Node elevations and site altitude.

o Loss data entered as L/D, Kt, or Cv.

o Treats pressure control, back pressure, differential pressure, and check-relief valves and dampers. Flow control valves are by MasoNeilan methods.

o Storage elements include reservoirs, tanks, and standpipes.

o Pumps and fans can be in parallel or in series. Pressures and fan curves are corrected for speed and altitude. Pump curves are corrected for wheel size, speed, and density.

o Mathematical flow functions for louvers, sprinkler heads, filters, cooling towers, silencers, etc.

o Simultaneous independent, multi-network solutions (up to 9 at a time) for what-if analysis.

o Make convenient pipe and duct sizing, fluid property vs. temperature data files.

Performance/design printouts:

At nodes -

o Elevation, external flow, pressure(s), temperature, density, viscosity, and vapor pressure.

o Pump/fan fluid power and adjusted performance curves.

At links -

o Hydraulic and equivalent circular diameters, crossectional area.

o Flow, velocity, velocity pressure, net positive head (for liquids with a defined vapor pressure).

o Hydraulic grade line (for civil engineers)

o Relative roughness, Darcy friction factor, total (friction) pressure loss.

o Net equivalent length, Reynolds number, flow vs. pressure derivative (sensitivity).

Operational features include:

o Log (saved to disk) of all input, solution display, and error messages (ASCII format). Can be read by word processor (included).

o Two levels of automatic output file backup.

o Extensive error trapping, with 150 warnings and messages.

o Interactive, run-time, program control.

o On-line input data form. Input data files may have unlimited comment, job documentation, heading, and blank lines.

o Works with any 80-column (or wider) printer.

Included is a 120-page manual containing more than 80 examples, many taken from published articles and handbooks. These examples are also provided in disk files.

Requires a math coprocessor (or 486+).

Two versions are available. They differ only in the number of links which can be handled.
