Transient and Water Hammer Analyses in Piping Lines (Basic)

Pressure change, change in fluid direction, fluid acceleration, or rapid energy transfer in fluid due to valve closing/opening, pump start-up/shutdown, tube rapture, etc. can be the causes of failure in piping systems. Fluid surge load, water hammer, cavitation, PSV loads, and induced vibrations may be dangerous for piping. If the hydraulic loads, as enumerated, exceed design allowable limits, or do not exceed the limits but occur repeatedly, the pressure boundary components will fail. This course provides for engineers the methods necessary to solve such problems and mitigate side effects of these phenomena. Rules of thumb method for estimation of hydraulic loads and consideration of such loads in design will be presented in this course. The mitigation methods like use of surge tank for release thermal-hydraulic loads will be discussed. This class is intended for engineers who are involved with such issues in power plants and/ or petrochemical industries. This course is a prerequisite for passing the advanced courses.
