contents We propose a validated fluid-structure interaction simulation framework based on strip methods for the vortex-induced vibration of a flexible pipe. The numerical results are compared with the experimental data from three previous steady flow conditions: uniform, linearly sheared, and bidirectionally sheared flow. The Reynolds number ranges from $10^4$ to $10^5$. The flow field is simulated via the RANS model, which is based on the open-source software OpenFOAM. The solid field is modeled based on Euler-Bernoulli beam theory, and fluid-structure coupling is implemented via a weak coupling algorithm developed in MATLAB. The vortex-induced vibration response is assessed in terms of amplitude and frequency, along with the differences in strain. Additionally, wavelet analysis and traveling wave phenomena are investigated. The numerical simulation codes and experimental data in this manuscript are openly available, providing a foundation for more complex vortex-induced vibration simulations in the future.
