EXPERIMENTAL STUDY ON PIPE FLUID INDUCED VIBRATION

This report discusses the outcome of pipe flow induced vibration. The objective of this
project is to have a study on pipe flow induced vibration and establish correlation
between vibration signal on various fluid flow conditions with various diameter pipes
and different types of fluids which simulates the present of scale in the pipe. This
understanding enables to bring benefits to the industry problem in terms of downtime
and low-cost. All the equipment, accelerometer, acquisition system has been
determined to be used in this experiment. The different size of PVC pipe diameter
ranging from 2.494 cm to 4.540 cm and the different types of fluids (water, diesel and
palm oil) are used. The result show clearly the range of valve opening effects the
acceleration signal on each accelerometer mounted. The vertical and horizontal axis of
the accelerometer on the pipe and accelerometer located at different points has shown
effect on the acceleration signal reading on the pipe walls. The acceleration signal noises
are increasing as the pipe diameter pipe decreasing. The graph patterns are changing as
the different types of fluids are used.
