Fluid transients software recommendation
Fluid transients software recommendation
(OP)
Hi all,
I am looking for a software to simulate fluid transients (mainly water and steam hammer in CCPP) with the following main features:
- Valid for compressible and incompressible simulations.
- With capabilities to define unbalanced forces in piping system (for a subsequent time-history analysis with other software i.e CAESAR).
Any recommendation based on your experience?
Thank you.

One possibility is PAULIN RESERACH GROUP BOSS Fluid http://www.paulin.com
BOS Fluids
BOS Fluids is an engineering software package that analyzes fluid transients in pipe systems and relates this information back to the mechanical piping system transferring the fluid.
For years, piping engineers have labored with simplifying hand methods, cumbersome analogue computers, or user-unfriendly software products when needing basic steady state and transient fluid analysis capability. BOS Fluids is written specifically to address the needs of the piping engineer for fluid reaction forces, and to provide a system whereby the fluid simulation results can be easily integrated back into the piping system design and analysis.
BOS Fluids is an interactive computer simulation package that models steady state and transient flow in liquid or gas carrying piping systems. The procedure is easy to use and interfaces with most pipe stress programs. The package contains the elements required to model most common unsteady flow conditions. The elements included in the simulation package are pipes, valves, pressure relief valves, vacuum breaker, air valves, pumps, equipment, surge vessels, inlets, outlets, and orifices. BOS Fluids makes fluid simulation simple and easily accessible and yet gives the analyst pressure transients and dynamic force results with an engineering accuracy.
The present friction model used in BOSFluids is Colebrook-White. The Darcy-Weisbach flow model is used for steady state pressure drop calculations and the basic theory applied in BOS Fluids can be found in Wylie & Streeter's "Fluid Transients" published by FEB Press. BOS Fluids is capable of simulating both the steady and transient behavior of liquid carrying closed conduit systems of pipes, valves, pumps and surge relief devices.
Typical analyses using BOS Fluids include:
• Water Transmission and Distribution Systems
• Main Cooling Water Systems for Chemical Plants
• Sewage Water Systems
• Combined Power and Drinking Water Cycle Power Stations
• Oil Product Transport Lines
• Tanker Loading and Unloading Systems
• Dynamic Behavior of Chemical Liquid Transport Lines
• Acoustic Analyses for Compressors and Pumps

I don't see where it specifically says it can be used for steam hammer and unbalanced force analysis. Do you have experience using BOS for those purposes?
BTW its sufficient just to post the web page link rather than a cut and paste.

RE: Fluid transients software recommendation
In fact I was focusing on BOS Fluids and Pipenet Transient (by Sunrise). The price difference between them is high.
Any expereince using these softwares? Advantages or disadvantages?
Anyone know which is the leader in this type of products?

Do you use any other software for fluid transients? Can you provide us with your feedback?
Thanks.

RE: Fluid transients software recommendation
I heard that you can predict/simulate unsteady state pressure escalation like hydraulic surges.

RE: Fluid transients software recommendation
which particular sort of waterhammer event are you trying to simulate?
- closure of turbine stop valve ( steam hammer)or bypass valve
--acceleration of excess water accumulation in LP bypass piping upon opening of LP bypass control valve
---other?
RE: Fluid transients software recommendation
I think that we need a software that can handle both compressible and incompressible flows but not necessary two-phase flow.
