“…The sluice body density is 2500 kg / m 3 , so as to calculate the displacement generated by the gravity of the sluice itself. Because of the symmetrical distribution of the sluice structure, half of its design is taken for modeling calculation [16]. The parallel solver developed here is tested of the solution scale, parallel efficiency, and iterative convergence of the system of equations, using the following solution environment: Intel (R) Core (TM) i5-8300H CPU @ 2.30GHz 2.30 GHz, which can run with 16.0 GB of memory.…”

“…This formulation is a solid (elastic) eigenstructure model proposed in the context of SPH, which relates the stress velocity to the deformation rate, but its disadvantage is that the law of energy conservation is not satisfied in the case of large deformations; so, in this paper, we study the case of a fluid-solid interaction in an isothermal state, and there is no need to consider the conservation of energy. The advantage of this is that it is possible to discretize the fluid and the solid at the same time in terms of both pressure and velocity [33].…”

In this paper, the fluid–solid interaction problem involving structural movement and deformation is considered, and an SPH (smoothed particle hydrodynamics) interaction method is proposed to establish a numerical fluid–solid model and to correct the particle velocities in the momentum conservation equations. It is found that, when the smoothing coefficient is equal to 0.93, the similarity of the free surface curves reaches up to 91.9%, and calculations are more accurate. Under the same working conditions, the classical model of elastic sluice discharge is established based on the SPH method and the finite element method, and the validity and accuracy of the model based on the SPH method are verified by analyzing the flow pattern of the sluice discharge, the opening of the elastic gate, and the change trend in the free liquid surface curve. On this basis, a number of characteristic points on the sluice gate are selected based on the SPH model to investigate the change rule of pressure at the fluid–solid interface, and the results are as follows: (1) based on the numerical model established by the SPH method, the flow pattern of the water, the opening of the elastic gate, and the change in the free liquid level curve are all in better agreement with the experimental results in the literature than those of the finite element method, and the computational results are also better; (2) the pressure of the solid on the fluid at each characteristic point is equal to the pressure of the fluid on the solid, which satisfies the principle of action–reaction and laterally verifies the nature of the dynamic boundary between the fluid and the solid, further verifying the validity of the program; and (3) in the process of sluice discharge, the elastic sluice presents a large force at both ends and a small force in the middle, meaning that the related research in this paper can act as a reference for flow–solid interaction problems related to sluice discharge.

“…25 The interaction of dam breaking flow with an elastic sluice was presented. 26 Violent movements of the water surface, hydraulic jump, breaking waves, static and dynamic impact are taken into account in the model. The results obtained numerically are then verified within an experimental model, obtaining a good agreement.…”

An analysis of the vibrations that may occur at the gate of a dam is proposed. Thus, the determination of an optimal constructive solution is sought from the point of view of vibration behavior. The dam gate is part of a constructive solution of an oscillating center pivot dam, which closes the gates if the downstream water level rises above a certain limit. This constructive solution is new. The gates are controlled by the water level. Such a system is easy to implement practically and the construction and maintenance costs are lower than in the case of classic dams. The problem that arises is that of the behavior of such a structure to vibrations. The eigenvalues of the gate structure are determined for a constructive solution proposed by the designers and the behavior of the forced vibrations that can stress the gate is studied. The analysis is performed for the case where the dam gates are closed. The work continues previous research on the structure's resistance to static loads and justifies the use of this solution in design. The method used to carry out the study is the finite element method. The advantages of the studied structure consist of lower costs for the proposed relatively simple constructive solution.
