Angular contact ball bearings (ACBB) are rolling bearings designed to support both axial and radial loads. The rolling elements (balls in this case) significantly decrease the power losses associated with rotating load bearing by replacing sliding with rolling. However, both the specific ...

The objective of this work is to analyze measuring techniques used in observation boreholes to investigate natural groundwater flow (magnitude and direction). The In-Well-Point-Velocity-Probe (IWPVP) is a technique based on mini tracer tests performed inside observation boreholes to ... En savoir plus

High temperature variations inside a tent can be a problem for campers’ thermal comfort. To increase user comfort, Decathlon has tents called "Fresh & Black (F&B)". The main improvement of this equipment lies in the textile technology, regulating the temperature inside and ... En savoir plus

Electret condenser microphones are one of the most used transducers for a variety of applications. The engineer designing these cartridges must take into consideration many factors to create a design that meets its specifications. Most parts of the design have multiple constraints across ...

In the frame of the decarbonization of steel industry, with the aim of creating new technologies and applications, RinaCSM developed for the EU project Horizon ModHEATech an electromagnetic-thermal model with Comsol Multiphysics in order to study the heating of a steel billet by ... En savoir plus

The electromagnetic pumping (EMP) of electrically-conducting fluid is of growing interest for many industrial applications requiring precise flow control, enabling stopping or reversing flow direction without any moving parts or mechanical devices. Presented in this work are the results ... En savoir plus

1 Problem Description Most studies for investigating heat and mass transfer phenomena in sorption storage systems use 1D or 2D numerical models. These are inadequate for analyzing processes in more complex geometries used in current prototypes. We present here a 3D model for the ... En savoir plus

Our atmosphere, land, and water are being continuously besieged by pollutants caused by such events as heavy metals leaching from mine tailing ponds, chemical spills from railroad and truck tanker accidents, and petroleum pipeline failures, to name just a few. These environmental insults ... En savoir plus

A digital twin is a virtual set of information replicating its physical counterpart at the utmost fidelity. Digital and physical twin benefit from bi-directional data exchange that occurs in real time and over the whole process lifecycle. Until now, experts in the design phase have ... En savoir plus

The aim of the present work is to explore through the developed numerical model the separation of exosomes from a more complex mixture of particles i.e. red blood cells and white blood cells, through combined acoustofluidics and fluid relocation in a bulk acoustic wave microfluidic ...
