Abstract
Studies involving two-phase flow are extremely important for the petrochemical industry. because the way in which the phases are distributed dictates the behavior of the gradient of pressure and quantities such as the heat transfer coefficients of the mixture, in addition to being relevant in flow assurance problems. Therefore, this work studies the fluid-structure coupling in two-phase flows in horizontal pipes by analyzing pressure and acceleration signatures. The results indicate a region of fluid-structure coupling from 2400 Hz to 3400 Hz, called coincidence frequency. Where the circumferential mode frequency of pipe is very close of resonance frequency of the bubble, in the liquid piston for intermittent patterns
