It is commonly recognized that careful thermal design of electronic equipments represents an unavoidable pre-production step in order to ensure reliability and performance of those components during their functioning. This paper mainly concerns a comparison between experimental and ... En savoir plus
The vibration of the walls of brass wind instruments has been a subject of study in the field of musical acoustics throughout the last decades. The amplitude of such vibrations, stimulated by the oscillating air pressure inside the instrument bore, is very small compared to the ... En savoir plus
Mixing is a typical unit operation that occurs almost in all chemical industries. Static – alternatively termed motionless – mixers are being widely used due to their low power consumption, low capital investment, minimal maintenance costs and versatility. The traditional helical mixing ... En savoir plus
Impact of human activities on the climate is evident, and the recent anthropogenic production and discharge of greenhouse gases into the atmosphere is highest in history. The current climate change have had worldwide influence on human and natural systems for example; global warming, ... En savoir plus
Finite element simulations performed through COMSOL Multiphysics are used to study the long-term performance of BHE fields placed in a water-saturated porous soil subjected to groundwater movement. The heat transfer problem is written in a dimensionless form and the long-term time ... En savoir plus
In this paper, a three-dimensional model of the coronary artery bifurcation is developed and physiological flow in the both healthy and stented coronary artery bifurcation is modeled using COMSOL Multiphysics. Wall shear stress induced by endovascular stents in the coronary artery ... En savoir plus
The mixing characteristics and residence time distributions (RTDs) of a staggered herringbone microchannel have been investigated numerically by COMSOL Multiphysics and by particle tracking algorithms that incorporate diffusion via a random walk. All simulations were validated with ... En savoir plus
Recently, electrokinetic flows have raised the interest of the scientific community. Driving flow with an electric field leads to promising applications for mixing, concentration, pumping application in lab on chips. However, current models are still inaccurate and don\'t fit the ... En savoir plus
An industrial pulp screen is investigated. The dilute pulp is pumped through a screen barrier. In order to avoid the fiber network to plug, it is necessary to 1) fluidize the shear thinning pulp 2) expose the barrier with plug releasing pressure pulses. This work involves a 2-step ...

At the 2006 Winter Olympics, the jump length difference between first and second place was only 5cm. This illustrates why ski jumpers are constantly tinkering with their posture in order to gain even the smallest of advantages. Experiments such as those shown in Figures 1 and 2 (b), ...
