Rafflo v7.0

Rafflo is a 32-bit pc-based program for simulation of pipeline hydraulics. It is intended for use in planning, design and studies of pipelines as encountered in oil and gas fields.

• Single and multi-phase simulations
• Calculate inlet pressure, outlet pressure, inside diameter, or flow rate in one-segment pipelines.
• Looping of pipeline segment in calculating inlet pressures.
• Choice of multiphase flow correlations
• Choose from Imperial, SI or Engineering units
• Computes velocity, liquid holdup, Baker parameters and determines Baker's flow regime
• Fluid-gathering pipeline systems up to 1 million nodes. Fluid properties from sources can all be different.
• Liquid grid systems networks that allow liquid input and draw-off (e.g. to an oil refinery) from the network
• Gas grid systems - networks that allow gas input and draw-off (e.g. to gas consumers) from the network.
• Dynamic determination of emulsification index and hence emulsion viscosity.
• Runs under Windows 9x and Windows NT 4.0
• User manual included as MS-Word 97 .doc files
