Fluid–structure interaction is ubiquitous in nature and occurs at all biological scales. Immersed methods provide mathematical and computational frameworks for modeling fluid–structure systems. These methods, which typically use an Eulerian description of the fluid and a Lagrangian description of the structure, can treat thin immersed boundaries and volumetric bodies, and they can model structures that are flexible or rigid or that move with prescribed deformational kinematics. Immersed formulations do not require body-fitted discretizations and thereby avoid the frequent grid regeneration tha

AbstractThe immersed boundary method has been extensively used to simulate the motion of elastic structures immersed in a viscous fluid. For some applications, such as modeling biological materials, capturing internal boundary viscosity is important. We present numerical methods for simulating Kelvin-Voigt and standard linear viscoelastic structures immersed in zero Reynolds number flow. We find that the explicit time immersed boundary update is unconditionally unstable above a critical boundary to fluid viscosity ratio for a Kelvin-Voigt material. We also show there is a severe time step rest

Extensive researches have been done for the interaction between open-type pile foundation structure and waves, including uplift force of wharf deck, horizontal force of structure and wave transmission behind breakwaters, among which wave transmission is mainly discussed in this paper. The wave transmission through a single immersed vertical barrier is analyzed by use of the physical model experiment; and an approximate formula to calculate the coefficient of wave transmission through a barrier is presented. Finally the wave damping effect of twin barriers is tested and analyzed.

ZnO with different morphologies were formed on Zn foils immersed in various concentrations of CuSO4 solutions. Then the specimens were heated at temperature of 200~600°C in air for 3h. The morphologies of as-prepared specimens were characterized by a scanning electron microscope (SEM). Water wetting angles on the specimens were measured. The results indicate that the morphologies of ZnO on the Zn foils relate to the CuSO4 concentration of in solutions. The morphologies on the specimens with dual-scale (nanoand micro) structure have higher wetting angles than those with flat structure. The wate

This study presents an experimental and numerical study of incident wave reduction and transmission coefficients for impermeable and permeable double submerged breakwaters. The experiments were carried out by constructing an immersed breakwater using gravel in a physical wave tank.

The transmission coefficient of the incident wave was small for the permeable submerged breakwater, and the smallest for the Bragg reflection condition with the gap of the b

In the planar flow casting process of amorphous strips, the flow behavior of molten metal and the inclusion content in the crucible are crucial to the morphology and magnetic properties of the material. This study conducts a comparative analysis of the effects of non-immersed and immersed funnels, as well as various funnel structures, on the fluid flow and inclusion removal efficiency in the crucible by integrating numerical and physical models. The findings reveal that for the same pouring flow rate, the diameter of the liquid column in non-immersed pouring conditions is smaller than that of

A number of numerical and physical model studies were used to assist in the design and future construction of the Oosterweel tunnel Project at Antwerp, Belgium. The tunnel will consist of 8 tunnel elements, to be immersed in water depths of up to 30m with ebb and flood tidal currents up to 2m/s. The design of the immersion and mooring systems are therefore a crucial part of the installation as well as understanding the effects of passing vessel on it, whilst in a temporary state before final back fill.

This study aims to investigate the vibration responses on underwater immersed tunnels caused by moving loads, taking into account factors such as the viscoelastic characteristics of riverbed water, foundation soil, and the immersed tunnel itself. An ideal fluid medium is adopted to simulate the water, while a saturated porous medium is used to simulate the riverbed soil layer. The immersed tunnel structure is simplified as an infinitely long viscoelastic Euler beam, and the vibration effects are described by the theory of the standard linear solid model, taking into account structural damping.

The paper presents a novel method for numerically modelling fluid–structure interactions. The method consists of solving the fluid-dynamics equations on an extended domain, where the computational mesh covers both fluid and solid structures. The fluid and solid velocities are relaxed to one another through a penalty force. The latter acts on a thin shell surrounding the solid structures. Additionally, the shell is represented on the extended domain by a non-zero shell-concentration field, which is obtained by conservatively mapping the shell mesh onto the extended mesh.

Resumo:

The immersed boundary method is a widely used mixed Eulerian/Lagrangian framework for simulating the motion of elastic structures immersed in viscous fluids. In this work, we consider a poroelastic immersed boundary method in which a fluid permeates a porous, elastic structure of negligible volume fraction, and extend this method to include stress relaxation of the material. The porous viscoelastic method presented here is validated for a prescribed oscillatory shear and for an expansion driven by the motion at the boundary of a circular material by comparing numerical solutions to an analytic

Black shale, which usually contains pyrite, is easily oxidized and generates acid discharge. This acidic environment is not favorable for concrete in engineering applications and is likely to affect the durability of engineering structures. This study investigated the effect of acid discharge from the weathering of black shale on the strength of concrete under partially immersed conditions. Black shale concrete immersion tests were conducted at different immersion depths to evaluate the oxidation conduction of black shale. Water chemistry and oxidation products were monitored during and after

AbstractConcrete structures suffer from cracking that leads to deterioration and shortening of service life. This is very critical for underwater structures, i.e., immersed bridge piles, immersed tunnel or submerged floating tunnels, which are consistently susceptible to ingress of harmful ions (chloride, sulphate and carbonate ions). Autonomous healing of concrete cracks can be beneficial to assure durability performance during the service life. In this context the paper presents a preliminary experimental activity carried out to study the self‐healing capacity of cementitious composites in m
