Analytical Investigation of Pipe of Tapered Thickness with an Internal Flow to Estimate Natural Frequency

Abstract

In this thesis, the effect of tapered thickness on the free transverse vibration of clamped – free pipe which have uniform circular cross section conveying water is determined analytically for two cases.The first involves the pipe which has a constant wall thickness at clamped end while the thickness at free end changes according to different thickness ratio. In the second case the thickness at free end is constant whereas the thickness at clamped end is changed at different thickness ratio. The pipe has a constant inner radius and length. The thickness ratios considered in this project are 0.2, 0.4, 0.6, 0.8 and 1.3D models of the pipe are done in Creo 2.0. CFD analysis, Static, Modal analysis is done in Ansys 14.5.
