Experimental and simulation study of flow induced vibration through straight pipes

Flow of a fluid through pipe can impose pressure on the walls of the pipe causing it to deflect under certain flow conditions. The deflection of the pipe may lead to structural instability in the pipe system which affects its efficiency. The present study deals with the effect of various parameters such as pipe diameter, pipe wall thickness, and volumetric flow rate (discharge) on the amplitude of pipe vibration in straight pipe for turbulent flow. An investigation is carried out by analytical, experimental and by simulation method to find the effect of these parameters on pipe vibration. DOE technique is used to know the effect of each factor i.e. pipe diameter, thickness and discharge on vibrational amplitude. It is observed that the amplitude of vibration increases with the increase in volumetric flow rate and slightly increases with the increase in diameter.
