“…6 For biomedical and biological applications, typical compliant structures such as vessels or membranes in strongly coupling problems have been studied by Lemmon and Yoganathan. 7 Many technological problems in engineering can be described using loosely coupling methods for FSI, such as industrial chimney, 8 turbomachinery, 9 bridges, 10 and so on. This study focuses on the case of FSI problems characterized by bluff body considering suspension system, when the local deformation is negligible compared to the displacement.…”

It is very important to study fluid-structure interaction of vehicles which move in strong crosswind environment. For solving a fluid-structure interaction problem, the effect of the deformation and vibration of the elastic body on the flow field should be considered. However, the reaction of the vibrating flow field on the vehicle body should be computed. A kind of coach model is selected for solving the fluid-structure coupling problem. We have considered the interaction of the deformation of vehicle suspension and the displacement of sprung mass and the flow field around the coach model using a numerical simulation. The coupling method is partitioned but loosely coupled with the Fluent software to describe the flow field and the ANSYS software to describe the reaction of the structure. The numerical results are in good agreement with the experimental data.

“…Other types of structures besides buildings have also been analysed. A 90 m steel chimney was analysed using a simplified FSI approach in Belver et al [19]. The approach here, has consisted in the calculation of the forces in 2D fluid planes based in the CFD theory combined with the proposed structural mechanical model.…”

Aims: On this work, a methodology that solves the fluid-structure interaction problem through load transmission method approach is presented. This methodology is applicable to any building's geometry, nevertheless, in order to develop a solution, it was proposed a building with a geometry not considered in design codes of structures under wind pressures. In order to compare the results of this methodology a tall building model widely studied by different authors is also analysed.

“…VIV is experienced in many situations; for instance, VIV on the cables of bridges, electric wires, high buildings, pipes, towing cables and mooring lines [12] subjected to vortex, and water currents may suffer fatigue damage. Thus the reduction of VIV has become a major topic in design engineering [13][14][15][16][17][18]. However, due to the fact that the concepts of focusing on collecting power by VIV are proposed in recent decades, it has to be taken into account in the design of microelectronics devices and electrical equipment like sensors requiring for sustaining power supply [6][7][8].…”

A concept of generating power from a circular cylinder undergoing vortex-induced vibration (VIV) was investigated. Two lead zirconate titanate (PZT) beams which had high power density were installed on the cylinder. A theoretical model has been presented to describe the electromechanical coupling of the open-circuit voltage output and the vibration amplitudes based on a second-order nonlinear Van der pol equation and Gauss law. A numerical computation was applied to measure the capacity of the power generating system. The lift and drag coefficient and the vortex shedding frequency were obtained to verify how the nondimensional parameter reduced velocityUraffects the fluid field. Meanwhile, a single-degree of freedom system has been added to describe the VIV, presynchronization, and synchronization together with postsynchronization regimes of oscillating frequencies. And the amplitudes of the vibration have been obtained. Finally, the vibrational amplitudes and the voltage output could go up to a high level in the synchronization region. The maximum value of the voltage output and the corresponding reduced velocityUrwere 8.42 V and 5.6, respectively.
