Simulation of an Adaptive Fluid-Membrane Piezoelectric Lens

H. Bettaswamy[1], U. Wallrabe[1]
[1]IMTEK, University of Freiburg, Germany

The expression <em>adaptive optics</em> was initially termed for the technology used in the telescopes to deform the mirrors to allow for phase correction of the incoming light. Soon, the adaptive optics was also implemented in microscopes, optical communication systems and ... En savoir plus

Study of Rotation of Ellipsoidal Particles in Combined Simple Shear Flow and Magnetic Fields

C. Wang [1], J. Zhang [1],
[1] Department of Mechanical and Aerospace Engineering, Missouri University of Science and Technology, Rolla, MO, USA

This study creates a 2D fluid-structure interaction (FSI) model to study the effect of magnetic field and particle aspect ratio on the period of rotation and symmetry of ellipsoidal paramagnetic particles. The results show that the magnetic field strength has a significant effect on the ... En savoir plus

A Multi-Physics Study of the Wave Propagation Problem in Open Cell Polyurethane Foams

M. Dossi [1], M. Brennan [1], M. Moesen [1],
[1] Huntsman Polyurethanes, Everberg, Belgium

Flexible and semi-rigid polyurethane foams are widely used as noise and vibration damping materials. Their porous random microstructure is composed of a visco-elastic frame structure with an interstitial fluid, normally air, filling the voids. The viscoelasticity of the foams is due to ...

Advanced Multiphysics Models for the Optimization of the Hot Extrusion Process of Light Alloys

R. Pelaccia¹, B. Reggiani¹, M. Negozio², S. Di Donato³, L. Donati³
¹DISMI - Department of Sciences & Methods for Engineering. University of Modena & Reggio Emilia
²DISTI– Department of Engineering for Industrial Systems and Technologies University of Parma
³DIN- Department of Industrial Engineering, University of Bologna

During the hot extrusion process, a cylindrical pre-heated billet is inserted into a container and is forced by a hydraulic press to flow through a shaped die in order to obtain, as final product, a profile with a constant cross-section (Fig.1). Aluminum extrudates have become prominent ... En savoir plus

Shock Boundary Interactions Generated by the Fin on a Semi-cylindrical Body

Jiawei Sun¹
¹Department of Mechanical and Aerospace Engineering, Tandon School of Engineering, New York University, Brookly, NY, USA.

This study investigates the shock boundary layer interaction occurring at the base of a double sharp fin. The base geometry is of particular interest, with comparisons made between flat and semi-cylindrical bases. The flow field is characterized via numerical simulations and ... En savoir plus

Visco-elastic Behavior of Cells in a Microfluidic Device using FSI

R. Schuster[1]
[1]University of Ulm, Germany

Variations of structure and shape of cells play an important physiological role. For instance, tumor and normal cells can be distinguished by elasticity, indicated by the amount of deformation under given stress. The mechanical characterization of a certain cell type is meaningful to ... En savoir plus

Biologic Tissues Properties Deduction Using an Opto-Mechanical Model of the Human Eye

A. V. Maurer [1], D. P. Enfrun [1], C. O. Zuber [1], R. Rozsnyo [2],
[1] R&D, Kejako, Plan-les-ouates, GE, Switzerland
[2] MNCM, HES-SO, GE, Switzerland

The visual accommodation is a complex biomechanical & optical process. Today in vivo imaging technologies do not allow to measure the eye components material properties, such as the refractive index or the stiffness: these properties are essential to understand and diagnose the ... En savoir plus

Static and Dynamic Deformations of a Reed Valve Immersed in Hydraulic Fluid

A. Chaudhuri[1]
[1]Los Alamos National Lab, Los Alamos, NM, USA

Metal reed valves are used for flow rectification in electrohydraulic pumps driven by smart materials at high frequencies but it is difficult to predict their behavior when the surrounding fluid has considerable inertia and viscosity. Simulation of this phenomenon involves modeling the ... En savoir plus

Chaining Dynamics of a Pair of Ellipsoidal Micro-Particles Under a Uniform Magnetic Field

J. Zhang[1], C. Wang[1]
[1]Missouri Univ of Sci and Tech, USA

Due to particle interactions, magnetic particles suspended in non-magnetic fields tend to form chains, clusters or columns under magnetic fields. The non-spherical magnetic particles in the suspension show different rheological properties compared to spherical particles. In this paper, ... En savoir plus
