Mechanical energy delivery during low-cycle system oscillation was studied by measuring the fluctuating pressure and flow rates at the inlet and outlet of a pump. By studying the relationship between the mechanical energy delivery versus flow patterns and observing the inlet and the inside of the impeller subject to cavitation, it was found that one of the causes of low-cycle system oscillation is the effect of cross sectional area reduction upstream of the impeller by the cavitation reverse flow. This is because a dynamic difference in phase between the cavitation volume versus inlet flow rate of the pump is a consequence of the above effect.
