One of the challenges associated with the wire-arc additive manufacture (WAAM) of metals is to provide adequate inert gas shielding, not only for the molten pool, but also for the long reactive metal surface that follows it. For Ti-6Al-4V, it has been shown that increased levels of ... En savoir plus

MEMS is the leading technology which combines both electronic and mechanical devices on a single microchip. Tracing the position of the object is an important problem in engineering. This can be addressed by Gyroscopes. These sensors are used to find orientation and angular velocity. ... En savoir plus

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 ... En savoir plus

A fully filled sphere of ferrofluid has constant demagnetizing factors in all three Cartesian directions such that when subjected to a uniform external rotating magnetic field the internal field is also uniform, and ultrasound measurements give no observable flow. Non-uniform magnetic ... En savoir plus

While the processes taking place in a bubble reactor are simple to describe in a few sentences it is much more difficult to give a physical description that is useful for engineering purposes. A better understanding of a cluster of bubbles dissolving in a liquid where the species ... En savoir plus

Digestion is the process of breaking down food into smaller components, by mechanical and enzymatic action in the digestive tract, so that the smaller nutrient molecules can be more easily absorbed in the intestinal tract. To study and analyze the human digestive process, different ... En savoir plus

INVELOX is an innovative wind power generation system as shown in Figure 1. It is comprised of a wind capturing system that accelerates and delivers high kinetic energy wind to a power conversion system placed in the Venturi section of the INVELOX. The objective of this project is to ... En savoir plus

The magnetic field gradient produced by an electromagnet gripper head depends on its design. Stochastic Methods offer certain robustness to the design optimization process. In this paper, Improved Discrete Particle Swarm Optimization (IDPSO) searching technique is applied to the shape ... En savoir plus
