“…Iwona Adamiec-Wójcik and Stanisław Wojciech studied the space model of the riser dynamics developed by the proposed method and its application through experimental and numerical simulation results. It is concluded that the movement of the upper end of the riser compensates for the horizontal movement of the base and stabilizes the force in the connection of the riser to the wellhead [151]. Wenlong Li et al evaluated the stability of the wellhead using composite casing by establishing a mechanical model.…”

Based on the whole life cycle process of the economic exploitation of natural gas hydrate, this paper proposes the basic problem of stabilizing the wellbore for the basic conditions that must be met to ensure the integrity of the wellbore for exploitation: revealing the complex mechanism of fluid–solid–heat coupling in the process of the physical exchange of equilibrium among gas, water, and multiphase sand flows in the wellbore, hydrate reservoir, and wellbore, defining the interface conditions to ensure wellbore stability during the entire life cycle of hydrate production and proposing a scientific evaluation system of interface parameters for wellbore integrity.

“…The traditional POD-Galerkin ROM is capable of solving FSI problems when the solid domains are treated as fluid domains [2]. The method for decoupling the solid domain is borrowed from the Finite Segment Method used for the dynamic analysis of a slender system, in which a continuous system is replaced by a system of rigid bodies that reflect the inertial features of the system modelled, as schematically shown in Figure 1 [30]. The segments are connected by means of joints consisting of massless and nondimensional springdamping elements that represent the stiffness characteristics of the link.…”

Fluid-structure interactions, especially full rotor simulations for wind turbines, are still computationally inefficient. Although the Proper Orthogonal Decomposition (POD) -Galerkin based Reduced Order Modelling (ROM) has become a popular tool to solve many fluid dynamics problems, most studies are limited to fluid flows in a fixed or infinite domain. The ROM, with either spatially or temporally adaptive snapshots, are still lacking in research, and in this paper, a POD-Galerkin based ROM for a FSI problem is proposed. The aim is to reduce the complexity of the costly solution techniques for solving the governing non-linear unsteady partial differential equations that govern the aerodynamic flows over fluid-solid systems with moving interfaces. This novel POD-based ROM is applied to several cases of plunging-pitching aerofoils as well as fluid-structure interaction simulations of a 3D vertical axis wind turbine full rotor simulation. For both applications, this model is shown to be very effective when performed with the proposed snapshot grids, thus reducing the computational cost while maintaining the same level of accuracy.

“…Since the 1970s, similar methods have also been developed: the segment method (SM) (Connelly and Huston 1994a, b;Xu and Wang 2012;Xu et al 2013;Adamiec-Wójcik and Wojciech 2018) and the rigid finite element method (RFEM) (Kruszewski et al 1975;Wittbrodt et al 2006;Drąg 2017;Adamiec-Wójcik et al 2021a). The main idea of the methods consists in dividing the flexible links (risers, ropes) into rigid elements (rfe), which assume the inertial properties (mass, mass moments of inertia) of a discrete element, and into massless and non-dimensional spring-damping elements (sde), which reflect flexibility and damping.…”

Dynamic analysis of risers often requires consideration of large deflections. One of the discretisation methods which includes analysis of large deflections is the rigid finite element method (RFEM). This paper presents a new, numerically effective, planar formulation of the method. The model takes into account large deflections caused by bending and longitudinal flexibilities. The models elaborated are, after validation, applied in calculations of static deflections and analysis of free frequencies of risers. Investigations are concerned with how a riser’s parameters (such as length and top/bottom supports), the sea current and internal flow all influence frequencies of free vibrations. Analysis of dynamics of a riser with and without an additional mass attached to the bottom of the riser is also carried out.
