Microfluidic devices allow creation of uniform droplets with a tight distribution. The COMSOL Multiphysics® software model presented ... En savoir plus

Introduction The topology optimization method is becoming increasingly popular as a design tool for multiphysics systems [1,2]. Topology optimization of fluid-thermal systems has been presented for example in [3] for forced convective heat transfer and in [4] for natural convection ... En savoir plus

Conventional swing is one phenomenon which a bowler uses to gain an advantage over the batsman. This study involved simulating conventional swing in the CFD Module of COMSOL Multiphysics® software and comparing the simulated results with experimental results of previous researchers. The ...

Analysis of burning candles is extremely complex; combustion produces a highly non-linear temperature profile through the flame in which local temperatures may exceed 1400 °C. Heat transfer includes radiation, conduction and convection components and the low melting point of the candle ... En savoir plus

Laser welding is often considered to be a superior technique over different conventional welding methods and has been gradually evolved as an efficient manufacturing process. It is a high energy density fabrication process and generally employed for fabricating intricate shapes/contours ... En savoir plus

Laser drilling of titanium and its alloys is widely used in aerospace industry, as it offers selective removal of material at high accuracy and speed. However, laser drilling often inherits defects such as large heat affected zone, micro cracks and recast layer. These defects depend upon ... En savoir plus

The Fibroscan® (Echosens, Paris, France) device based on vibration–controlled transient elastography (VCTE) is used to non– invasively assess liver stiffness correlated to the hepatic fibrosis. Stiffness is quantified by measuring the velocity of a low–frequency shear wave traveling ... En savoir plus

Nanofluids is a new class of fluid consisting of particles in a liquid. Different base liquid has been proposed and the most common one is water. The concentration of these particles can range from 0.1% to 5% or greater. Different numerical models have been proposed to solve this ... En savoir plus

Additive manufacturing gathers technologies where near net shape components are produced by depositing successive layers of materials. Among these technologies, the Layer Beam Melting (LBM) process – often referred to as Selective Laser Melting (SLM) – is garnering industrial interest, ... En savoir plus
