Abstract
Vibrations in pipelines are common in systems with alternative pumps due to the fluctuating and pulsating flow generated by these devices. Flow attenuators are installed to reduce these vibrations by absorbing the pressure and flow oscillations produced by the pump. The efficiency of flow attenuators can be enhanced by adjusting geometric parameters, such as thickness, and by arranging them in series. This study analyzed the behavior of series-connected flow attenuators, varying their thickness, to investigate the differences in flow fluctuation attenuation and distribution. Numerical simulations were conducted using specific software. Two geometric configurations of attenuators were considered: a straight tube and a variation consisting of sections connected in series. The thickness of the attenuators ranged from 1 to 3 mm. The results showed that the thickness of the series-connected attenuators significantly influences flow fluctuation attenuation. Thinner attenuators yielded better results. Geometric modifications and the arrangement of attenuators are decisive factors in optimizing system performance, resulting in performance improvements in process units that employ alternative pumps.
