The current general context for green production and decarbonation prompts considering alternative solutions to produce high added value byproducts from gas decomposition without producing CO2. Steam Reforming or Combustion processes, widely applied in Industry, need H2O or O2 to ... En savoir plus

Solenoid valves control fluid flow by using the passage of an electric current to produce a magnetic field that controls the displacement of a pre-tensioned plunger. As the electric current increases, the induced force causes the plunger to move upward against the force exerted by a ... En savoir plus

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

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

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

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

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

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

This paper explores the complexities of a dragonfly's flapping wing motion. It includes the literature as well as analytical results using simulations done in COMSOL Multiphysics® software. The study depicts the Fluid-Structure Interaction of the 2D wing (airfoil) with air, governed by ... En savoir plus

In this paper simulation and parametric study of a PDMS valveless micropump using Fluid-Structure Interaction (FSI) appraoch is presented. The simulation for the valveless micropump were carried out in COMSOL Multiphysics software. In case of a valveless micropump diffuser/nozzle element ... En savoir plus
