This paper presents a review on some developments of numerical methods for linear and nonlinear fluid-solid interaction (FSI) problems with their applications in engineering. The discussion covers the four types of numerical methods: (1) mixed finite element (FE)-substructure-subdomain model to deal with linear FSI in a finite domain, such as sloshing, acoustic-structure interactions, pressure ...
UNLABELLED The latest methods in estimating the probability (absolute risk) of osteoporotic fractures include several logistic regression models, based on qualitative risk factors plus bone mineral density (BMD), and the probability estimate of fracture in the future. The Slovak logistic regression model, in contrast to other models, is created from quantitative variables of the proximal femur ...
We consider in this paper numerical approximation of the linear fluid-structure interaction (FSI). We construct a new class of pressure-correction schemes for the linear FSI problem with a fixed interface, and prove rigorously that they are unconditionally stable. These schemes are computationally very efficient, as they lead to, at each time step, a coupled linear elliptic system for the veloc...
The recent TJLAB experimental data on inclusive electron scattering at high momentum transfer from complex nuclei are analyzed in terms of y scaling, taking into account the final state interaction (FSI) of the struck, off-shell nucleon. It is shown that at large negative values of y (x > 1), the Q2 dependence of the FSI is mostly driven by the elastic nucleon-nucleon cross section, and that, a...
With the diquark structure of Λc, we investigate the branching ratios of Λc → nπ and pπ. The results show that without considering the final state interaction (FSI), the branching ration of Λc → pπ is only of order 10−6 whereas taking into account the FSI effects, this ratio could reach 10−4 and is at the same order as Λc → nπ. Concrete values depend on phenomenological parameters adopted in th...
We critically analyze recent attempts to include final state interaction (FSI) effects in the calculation of the CP violating ratio ε/ε. In particular the approach of using the Muskhelishvili-Omnès equation for the decay amplitudes is examined. We find that the values of the dispersive correction factors are very sensitive to initial conditions which are, at present, out of control, and demonst...
InClusive electron scattering data on 3He and 3H are analyzed under full treatment of the final state interactions (FSI) using realistic nucleon-nucleon forces. The data are well described. We use two different methods, one where we calculate the pd and ppn breakup contributions separately and another one which is related to the optical theorem for Compton scattering. Both rely on precise solut...
For many applications, the ability of a foil to passively adapt to the experienced fluid loading could be advantageous, Nicholls-Lee & Turnock (2007): e.g. wind or tidal turbine blades, hydrofoils for sailing yachts, or marine propellers. Composite materials provide the opportunity to tailor the bend twist coupling of a structure to achieve these goals, Veers & Bir (1998). To allow such foils t...
This contribution is the second part of two papers on the Fully Eulerian formulation for fluid-structure interactions (fsi). We present different fsi applications using the Fully Eulerian scheme, where traditional interface-tracking approaches like the Arbitrary LagrangianEulerian (ALE) framework show difficulties. Furthermore, we present examples where parts of the geometry undergo a large mot...
