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.

The results indicate that the morphologies of ZnO on the Zn foils relate to the CuSO4 concentration of in solutions.

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.

The objective of this thesis is to further extend the application range of immersed computational approaches in the context of hydrodynamics and present a novel general framework for the simulation of fluid-structure interaction problems involving rigid bodies, flexible solids and multiphase flows. The proposed method aims to overcome shortcomings such as the restriction of having to deal with similar density ratios among different phases or the restriction to solve single-phase flows. The new framework will be capable of coping with large density ratios, multiphase flows and will be focussed

Nowadays the construction of palm oil industry mills is advancing rapidly and the next one is Refined Palm Oil (RPO). Refined Palm Oil (RPO) is one of the derivatives of palm oil processing. One option to use structures in the construction of palm oil mills is to use concrete. Plant parts that have concrete components often suffer damage, cracks and reduced concrete strength.This study is intended to examine the mechanical properties of concrete including compressive strength, flexural strength and porosity in concrete in the RPO environment, examining changes in the weight of coarse and fine

Abstract The aim of this research is to assess the corrosion performance of galvanized reinforcing bars in concrete elements exposed to natural tropical marine environment in the Mexican Caribbean, using limestone aggregates and ordinary Portland cement (OPC). Reinforced prisms of concrete with water to cement (w/c) ratios of 0.4, 0.5, 0.6 and 0.7 were half-immersed in seawater at a seashore site in the Yucatan Peninsula (Sisal). Corrosion was monitored by corrosion potential and linear polarization resistance measurements. The chloride penetration in the concrete was also measured. Corrosion

Abstract This article focuses on sacrificial anode cathodic protection design and analysis for near shore steel-fixed pipe type piling structures. The electrolyte resistivities along the immersed and buried portions of a marine pile can vary by several orders of magnitude. A single pile can be exposed to extreme resistivity differences. The higher resistivities in the mud zone make it less attractive to receive protection, especially with increasing depth below the mud line. Additionally, coating is typically not applied to most of the surface area below the mud line. The industry accepted des

Abstract Corrosion protection of structures operating in seawater is usually provided by cathodic protection (CP) by sacrificial anodes, often in conjunction with protective organic coatings. However, these methods have some limitations. Organic coatings, when used without CP, can provide protection to steel only when intact and anodes not only significantly increase the overall mass of the structure, but also have to be replaced periodically. An alternative corrosion mitigation method is the application of thermally sprayed metallic coatings, such as Al, Zn and ZnAl, which work as a barrier t

Natural polymer blend films composed of chitosan and silk fibroin were prepared by solution casting technique with various ratios of chitosan to silk fibroin, using glutaraldehyde as crosslinking agent. The effects of the ratio of chitosan to silk fibroin and crosslinking agent on mechanical properties, swelling behavior and drug releasing property of the blend films were studied. For the swelling behavior, the blend films exhibited a dramatic change in the degree of swelling when immersed in acidic solutions. The blend film with 80% chitosan content had the maximum degree of swelling. It appe

"Cold-formed steel (CFS) self-drilling screw connections are popular in the construction industry due to rapid fastening and ease of installation. However, the corrosion damage of CFS structures can significantly reduce mechanical properties, affecting the safety and durability of such structures. Therefore, this research investigates the effect of corrosion on the behavior of CFS connections experimentally. This paper presents a total of 36 new experiments on different types of CFS self-drilling screws (12 and 14 gauge) and steel sheet thickness (2.5 mm). Half of the tests were for corroded s

The immersed tunnel of Shenzhen-Zhongshan Link Project adopts the steel shell-concrete (SSC) composite structure, in which the two-way stiffened steel plate is applied as the surface of steel shell. Since the steel plate stiffened in two-way, the residual stresses could be induced in the complicated welds at the intersections of plates and stiffeners. Therefore, residual stress experimental study on two full-scale specimen of the two-way stiffened steel plate, based on the steel shell details of ShenzhenZhongshan Link Project, was carried out to investigate the distribution of residual stresse
