Fluid/Piping Interaction

Fluid transients such as pressure surge (waterhammer), slugging or pulsations arise inside piping systems. These fluid transients can give rise to larger stresses than during the steady state case or cyclic loadings that may mean that fatigue failure becomes an issue. Analyzing these scenarios, which can be critical for the safe operation of a plant, means coupling the mechanical design of a system with a solid understanding of the transient phenomena inside the pipe.

 

Using our extensive consultancy experience in accounting for fluid transients within piping design, DRG has created this two day training course. During this 2-day training course the participants will be shown how to model fluid transients, for example how large is the pressure surge due to the closure of a valve or the pulsation amplitude downstream of a pump? Here the commercially available DRG software packages BOSfluids and BOSpulse, in which no prior knowledge is required, will be used to help the participants understand and explore different fluid transient phenomena arising in piping

 

These fluid transients will then be used as a boundary condition in a piping flexibility study. Discussion will be had on the benefits of a quasi-static or dynamic study, before the participants gain first-hand experience in incorporating the pressure transients generated in BOSfluids and BOSpulse into a piping mechanical response analysis. Here the different types of analysis and code compliance options will be explained for one-off and cyclic transient loads. The piping stress package CAESAR II v7.0 will be used for the mechanical analysis and the participant will also become familiar with the import/export coupling between BOSfluids and BOSpulse, and CAESAR II.

 

The training course will be given by an experienced trainer from DRG, who regularly works on projects in which fluid transients are incorporated in a piping code compliance check. The trainer is also actively working with the software development team to improve the DRG fluid transient software packages further.

Intended for:

  • Engineers in the field of dynamic analysis of piping systems
  • Understanding the interaction between fluid transients and mechanical design
  • Engineers who use BOSfluids or BOSpulse
