Vortex-induced vibrations (VIV) are caused by fluid flowing past a structure, such as a cylinder or tube, creating vortices that cause the structure to vibrate. This phenomenon may cause fatigue and structural damage in fluid conveyance tubes, among other unfavourable outcomes. Fluid conveying is the process of moving gases or liquids over a network of tubes, pipelines or other conduits. Moving fluids from one place to another for a variety of uses, like distribution, processing or transportation, is a basic component of many industries, including manufacturing, oil and gas, plumbing, and manufacturing. It is vital to design and develop such systems to mitigate VIV using methods like dampers, strakes or changing the tube's geometry because this cyclic loading can degrade the structure over time. In this study, a numerical approach was used to assess the vortex-induced vibration caused by obstacles inside a fluid conveying tube. Effect of fluid domain as pressure on fluid solid interface and solid domain was investigated numerically using ANSYS software. ANSYS modules such as Fluent, Transient Structural, Modal and Harmonic response were utilised to find out the deformation, modal shapes, critical frequencies and frequency response function. When the tube and flow are designed such that the vortex shedding frequency matches the tube’s natural frequency, the tube undergoes excessive vibration due to resonance.
