Xram

Xram i a shell for using the programs PFC-SF (Pipe Flow Calculations - Staedy Flow)
and PFC-TF (Pipe Flow Calculations - Transient Flow)
The programs are able to simulate staedy and transient flow beahvior in complex pie systems.






Features :
Numbers of pipes : at least 2000
Numbers of pumps : at least 100
Heater/Boiler/Cooler : at least 30
Valves : at least 350

The program was originally made by Bror-Arne Gustafson, Chalmers University of Sweden, and has continously been developed since 1985.The main features with the programs are that they are able to simulate almost any pipe system with incompressible flow. The programs are for experts. The field of systems and components that can be simulated is comprehensive. Even though they are user friendly and easy to use, not much work has been done to make them look commercial. The programs are for sale, by us. But, If your need of analyse not is extencive, we recommend you to ask for us as consultans.

Examples of abilties included :
Four quadrant pump cuves Necessay in transient calculations
Controlled valves and pumps Necessary when dealing with complex systems
Pressure head movies A lot of examples on the main page
Automated calculations Gives energy and volume instead of effect and flowrate


Examples of systems that have been simulated :
Ink Jet Printer : Transient bevior
Diesel injector : Transient behavior when using ethanol as fuel
Mine pumping : Minimize and secure waterhammer effects after pump trips
Wind system on 16th century organ resarch project
District heating systems : Simulate and analyse staedy and transient flow beavior


The programs are used by several district heating distributions companys, such as in Stockholm and Gothenburg, who use them frequently in their planning. The programs are also our main tool for consulting in the field of analysing complex pipe systems.
