Forced vibration of a fully immersed pipe aspirating water: Experimental investigation

This study experimentally investigates the dynamics of a fully immersed pipe aspirating water under horizontal excitation at the upper end. The experiment is conducted to examine the effect of the internal flow velocity and the different inlet shapes, straight, bellmouth, T-shape, and L-shape, on the frequency response characteristics of the pipe. Through a series of experiments, it is found that a non-dimensional internal flow velocity at U = 3.8 significantly changes the response characteristi
