Abstract:

This article reviews finite element methods that are widely used in the analysis of solids and structures, and they provide great benefits in product design. In fact, with today’s highly competitive design and manufacturing markets, it is nearly impossible to ignore the advances that have been made in the computer analysis of structures without losing an edge in innovation and productivity. Various commercial finite-element programs are widely used and have proven to be indispensable in designing safer, more economical products. Applications of acoustic-fluid/structure interactions are found w

Abstract:

The type, association, variations, and valence states of several metal elements of scheelite can trace the source and evolution of the ore-forming fluids. There are four types of scheelite from the Xiaoyao deposit: (1) scheelite intergrown with garnet in the proximal zone (Sch1a) and with pyroxene in the distal zone (Sch1b), (2) scheelite replaced Sch1a (Sch2a) and crystallized as rims around Sch1b (Sch2b), (3) quartz vein scheelite with oscillatory zoning (Sch3), and 4) scheelite (Sch4) within micro-fractures of Sch3.

Abstract:

AbstractHow to effectively simulate the interaction between fluid and solid elements of different sizes remains to be challenging. The discrete element method (DEM) has been used to deal with the interactions between solid elements of various shapes and sizes, while the material point method (MPM) has been developed to handle the multiphase (solid-liquid-gas) interactions involving failure evolution. A combined MPM-DEM procedure is proposed to take advantage of both methods so that the interaction between solid elements and fluid particles in a container could be better simulated. In the propo

Comprehensive studies on effect of fluid-structure interaction and dynamic response for tension structure were conducted by the numerical simulation. An iterative coupling approach for time-dependent fluid-structure interactions is applied to tension membranous structures with large displacements. The coupling method connects a flow-condition-based interpolation element for incompressible fluids with a finite element for geometrically nonlinear problems. A membranous roof with saddle shape exposed to fluctuating wind field at atmosphere boundary layer was investigated for the coupling algorith

Element exchange and enrichment during fluid-rock interactions are common, providing potentially novel proxies to trace hydrocarbon migration in addition to the traditional organic geochemistry tracers. However, the processes, mechanisms, and geological and geochemical fingerprints of these interactions are complex, hampering the applications of hydrocarbon migration tracers. To investigate such interactions, we conducted a petrological, mineralogical, and in situ and bulk geochemical study of authigenic quartz and whole-rock samples from the Mahu Sag, northwestern Junggar Basin, northwest Chi

Fluid-filled fractures involving kinks and branches result in complex interactions between Krauklis waves—highly dispersive and attenuating pressure waves within the fracture—and the body waves in the surrounding medium. For studying these interactions, we introduce an efficient 2D time-harmonic elastodynamic boundary element method. Instead of modeling the domain within a fracture as a finite-thickness fluid layer, this method employs zero-thickness, poroelastic Linear-Slip Interfaces to model the low-frequency, local fluid–solid interaction. Using this method, the scattering of Krauklis wave

The required input parameters, dynamic loads, and system properties for such problems are not in general well-defined and can be considered random variables.

Immersed methods are considered as a class of nonboundary-fitted meshing technique for simulating fluid–structure interactions. However, the conventional approach of coupling the fluid and solid domains, as in the immersed boundary method and the immersed finite element method, often cannot handle high Reynolds number flows interacting with moving and deformable solids. As the solid dynamics is imposed by the fluid dynamics, it often leads to unrealistically large deformation of the solid in cases of high Reynolds number flows.

In the field of plastic extrusion, the accurate feeding of materials to the extrusion process is an important issue.

Therefore, the understanding of the relationship between the feeder and the extruder is very important. This paper presents and analyzes this relationship. The feeder is usually a separate and distinct item from the extruder. The feed materials and the environmental conditions may affect the flow rate of the reaction or blending process of the extrusion process.

This paper presents a novel approach utilizing the discrete element method (DEM) and smoothed particle hydrodynamics (SPH). A new fluid–structure coupling method called the common-node discrete element method–smoothed particle hydrodynamics (DS–SPH) is proposed. The DS-SPH method involves establishing a DEM and SPH method on the same node to create common-node discrete element-smoothed particle hydrodynamics (DEM-SPH, DS) particles. This enables the DEM particles to experience forces exerted by the SPH particles within their supporting region through the SPH particles located at the same node.

Abstract:

Abstract Niobium and tantalum, rare metals and high field strength elements (HFSEs) that are essential to modern technologies, are concentrated among others in lithium-cesium-tantalum (LCT) pegmatites and rare metal granites. The most important hosts for Nb-Ta in these types of deposits are the columbite group minerals (columbite-tantalite), but at some ore deposits significant Ta is also contained in wodginite, microlite, and tapiolite. Previous solubility experiments of HFSE minerals have been limited to high temperatures because of the slow diffusivities of HFSEs in granitic melts. An exper

Abstract:

Based on acoustic fluid elements, a dynamic analysis of liquid sloshing modes and liquid-filled containers was undertaken, considering the effect of fluid–structure interactions (FSIs). The liquid sloshing modes in two-dimensional (2D) and three-dimensional (3D) containers were analyzed, and the results were compared with liquid sloshing modes measured in tests and theoretically calculated modes. This finding thus verifies the correctness of the simulation method based on acoustic fluid elements. Cylindrical liquid-filled containers with different water levels were subjected to a modal analysi

Abstract:

This numerical study delves into the dynamic interaction between reservoir heterogeneity and its impact on the dual objectives of geothermal energy extraction and CO2 sequestration. Employing finite element models, this research scrutinizes the effects of variable porosity, permeability, and capillary entry pressures on fluid dynamics and thermal processes within geothermal systems. Key findings reveal that these heterogeneities significantly dictate fluid behavior and heat distribution, influencing the operational efficiency and environmental sustainability of geothermal–CO2 storage operation

Abstract:

Calculating bending vibrations of centrifugal pump rotors, stability and unbalance response are of major interest. In order to predict the dynamic behavior accurately, one has to take into account the coupling mechanisms between the vibrating shaft and the surrounding fluid. This paper presents a finite-element procedure which includes the fluid forces arising from journal bearings, seals, balance pistons and impeller interactions to the dynamic calculations of turbopumps. The theoretical background is briefly explained and a simple Jeffcott rotor is used to show several effects of these fluid

Theoretical development of a mixed finite element substructure—subdomain method for dynamic analysis of fluid—structure interaction systems (FSIS) with applications in maritime engineering is summarized in this paper. Governing equations for FSIS are presented. Boundary conditions for air—liquid interfaces are formulated to account for mass density discontinuity of different fluids. The frequency shift technique is demonstrated for FSIS, which establishes a basis for the design of an algorithm for the purpose of dynamic analysis of structure, fluids, and their interactions.

Abstract:

Interaction of an oscillating membrane with a fluid is important because the wide variety of technological applications. A boundary element method has been employed for the analysis of a vibrating rectangular membrane in contact with a compressible fluid at rest. The deformation modes of the membrane correspond to the vacuum case. For the calculation of the pressure jump over the membrane, the Helmholtz’s integral equation for the fluid pressure is employed taking into account the fluid-membrane interface boundary condition. Considering the membrane equation and applying a collocation method,
