Biofluid-Structural Interaction in Abdominal Aortic Aneurysm for Predicting Timeline to Rupture: The Effect of Hypertension and Aorta Wall Material Properties new

K. Cluff[1], H. Mehraein[1], G. Jayakumar[2]
[1]Bioengineering, Wichita State University, Wichita, KS, USA
[2]Industrial & Manufacturing Engineering, Wichita State University, Wichita, KS, USA

An abdominal aortic aneurysm (AAA) is a bulge formed in the large blood vessels that supply blood to the abdomen, pelvis, and legs. A fluid structure interaction model was developed in a 3D aortic aneurysm model, which was constructed from abdominal CT scan images. Combining medical ... Per saperne di più

Design of High Performance Micromixer for Lab-On-Chip (LOC) Applications

K. Karthikeyan[1] , L. Sujatha[1]
[1]Rajalakshmi Engineering College, Chennai, Tamil Nadu, India

This paper presents the design and simulation of micromixer for Lab-On-Chip (LOC) applications. There are two types of micromixers: one is an active micromixer and another one is a passive micromixer. This paper investigates microfluidic flow characterization and mixing rate of two ...

Simulation of Microstructured Rolling-Sliding Contacts new

M. Weschta[1], S. Tremmel[1], S. Wartzack[1]
[1]Engineering Design, Friedrich-Alexander-University Erlangen-Nürnberg (FAU), Erlangen, Bavaria, Germany

To reduce friction in lubricated tribological contacts, the surfaces of the contacting bodies can be microstructured to improve lubricating conditions. For lower loaded contacts this approach has already reached industrial applications, e.g. the piston-liner contact. For higher loaded ... Per saperne di più

Drag Fluctuations of a Fully Deployed Flow Actuator Embedded Inside Turbulent Boundary Layer Flow new

Dr. A. Elzawawy[1]
[1]Engineering & Technology Department, Vaughn College of Aeronautics & Technology, Flushing, NY, USA

Introduction: In this work, a CFD model of 2D flow around a fully deployed flow actuator was developed using COMSOL Multiphysics® software and the CFD Module. The results of COMSOL modeling is also compared with the experimental data of the same dimensions actuator. The 100mmX2mm ... Per saperne di più

Stress Evolution due to EM in Metal Line Confined: Model and Correlation with Experiments

G. Marti [1], L. Arnaud [2], Y. Wouters [3]
[1] STmicrolectronics & Univ. Grenoble Alpes-SIMAP, France
[2] Cea-Leti Minatec, Grenoble, France
[3] Univ. Grenoble Alpes-SIMAP, Grenoble, France

Electromigration induced failure is one of the main reliability issues for the microelectronics industry. The continuous scaling of the interconnect dimensions leads to higher operating current densities and temperatures, which accentuates the electromigration failure. As a consequence, ...

The Analysis of the Conditions of Flow in the Tundish Performed by a Numerical and Physical Method

T. Merder [1], J. Jowsa [2], A. M. Hutny [2], J. Pieprzyca [1], M. Warzecha [2],
[1] Silesian University of Technology, Katowice, Poland
[2] Czestochowa University of Technology, Czestochowa, Poland

Studies of the liquid metal movement (hydrodynamic) in a real object (tundish) are substantially precluded due to the objective difficulties (high temperature and the size of metallurgical equipment), compared to their execution by the use of physical and numerical modeling. In presented ... Per saperne di più

Numerical Simulation of Acoustic Properties of Porous Metals under High Sound Pressure Level Conditions

B. Zhang [1], X. Wang [1], L. Ni [1]
[1] School of Mechanical Engineering, Ningxia University, China

The sound propagation and absorption properties in porous media under high sound pressure level conditions have been reported elsewhere. Also several analytical and semi-analytical solutions have been developed; however, these solutions are relatively complicated and the provided results ... Per saperne di più

The Bio Inspired Tactile Sensor

N. Sabri [1]
[1] Universiti Malaysia Perlis, Malaysia

In recent years, studies on robotics have been needed, to utilise the tactile sensors for artificial skin. Researchers have been working on tactile transduction technologies which lead to many sensor prototypes and devices for robotic applications in their effort to solve the tactile ...

A COMSOL Multiphysics® Software Analysis of Beam Tube Cooling in the High Flux Isotope Reactor of ORNL

J. D. Freels [1],
[1] Research Reactors Division, Oak Ridge National Laboratory, Oak Ridge, TN, USA

Previous to the present work, a formal calculation was approved [1,2] to support the operation of the High Flux Isotope Reactor (HFIR) Horizontal Beam-Tube 1 of 4 (HB-1). The present calculation [3,4] repeats the previous work using COMSOL Multiphysics® software and extends the analysis ... Per saperne di più

Optimization of Drying Step to Obtain Large, Transparent Magnesium-Aluminate Spinel Ceramics

J. Petit [1], L. Lallemant [1],
[1] ONERA, Chatillon, France

To obtain large transparent ceramic samples, we optimized the drying step process using COMSOL Multiphysics®. Indeed, green body's drying in a climate chamber is the critical step when large size and complex shape samples are needed. Then we obtained 75 mm diameter and 10 mm thickness ... Per saperne di più
