Analysis of Flow‐Induced Vibrations in an Air Compressor Piping System

Air compressors are essential to our day‐to‐day life since they find applications in every part of our lives. Compressor systems experience various problems during operation. Vibration is one of the crucial threats to their reliable operation. This study investigates vibration behavior in compressor piping systems using a fluid–structure interaction (FSI) approach. A coupled ANSYS–FLUENT model was developed to predict the dynamic response under operating conditions. The analysis revealed that the first bending mode occurs at a natural frequency of 205.16 Hz, with a maximum vibration amplitude of 7.72 × 10 −2 mm and peak pipe deformation of 0.0299 mm at the first bend. The highest von Mises stress was 55.05 MPa, concentrated near the bend. These results demonstrate that the proposed FSI methodology accurately identifies resonance risks and stress hotspots, providing a reliable basis for vibration mitigation and structural integrity assessment in compressor piping design. It has been observed that the proposed methodology is a useful tool to predict the vibration phenomena under various operating conditions.
