Abstract
Dynamic forces induced by turbulent flow are one of the most common sources of piping vibration. Excessive vibration can lead to pipe failure and immoderate noise. Piping fittings tend to cause disturbances in the flow profiles, increasing the turbulence and hence the pipe vibration. This paper compares the influence of pipe fittings (e.g. long and short radius elbows and orifice plates) on the turbulence in single-phase fluid flows and its effects on pipe vibration, using both numerical and experimental approaches. Results from CFD analysis using the k-ε model and experiments with different pipe fittings are presented.
