“…Solving and analyzing FSI problems afford some complexities. For this reason, experimental and numerical approaches are mainly employed by researchers for FSI analysis in different areas, such as an elastic cylinder exposed to a fluid flow [1], rotation of an elastic rod in a viscous fluid [2], free vibration of a curved rod in a fluid flow [3], pipe systems [4,5], cycloidal pump [6], beam deformation in two-phase flow [7], and incompressible multiphase flow problem [8]. In addition, the importance of considering FSI effects was studied by [9].…”

This paper presents a novel approach for simulating the interaction of long elastic rod strings and the corresponding fluid flow around in sucker rod pump systems. The governing equations of transient multiphase fluid flow are coupled with those of the rod string deformation to improve the numerical analysis of sucker rod pump behavior. For the first time, transient water-oil-gas multiphase fluid flow containing dissolved gas is related to the rod cyclic loads by the proposed numerical simulation. The mathematical model derived incorporates the dynamics of the rod string and the multiphase fluid flow. Downhole loading of the rod is applied based on the transient pressures of the moving gas-liquid flow in the annular space and the barrel under the plunger, considering different modes of pump operation. A two-way algorithm for fluid and solid zones is developed to enhance the performance of the current simulation and reduce the complexity of solving process. Several test cases have been analyzed using the proposed simulation method. The obtained results show good agreement when they are compared and validated with the available numerical and experimental results.
