Abstract
Pipeline system performance analysis is idealy suited for computer application to allow for evaluation of the multiple variation which impact a ”Pipeline System ” Several computer packages exist which combine the technical variables analysis necessary to model fluid flow through a piping system. Most of these existing packages, however depend on text/data file input processing which is complex and time consuming with output tedious to use and interpret, so, such method is required to visually display input/output to allow user to better understand total pipeline network.
The purpose of this work is then to develop and document an integrated system for network analysis application with visual computer aided drawing output to simplify analysis and interpretation of pipeline modeling analysis.
The model developed herein is a computerized numerical simulation of the network in conjunction with customizing one of the most widely used graphical packages, AutoCAD, to draw a completely network or to amend an existing network. A separate program has been designed to capture the network geometry and different components data and characteristics and create a data file for further processing by the numerical model of the network, the output is processed by another program to include the results in the drawing database which is visualized in the drawing mode again.
The networks considered are assumed to consist of ideal conduits (pipes), source pumps, booster pumps, pressure educing valves, pressure sustaining valves, non-return lves and reservoirs. Each idealized component is assumed pe governed by specific characteristic flow formula which cases is nonlinear and the set of equations are the modified Newton iteration method.
