Helicon Injected Inertial Plasma Electrostatic Rocket (HIIPER) [1] is a plasma thruster being researched at University of Illinois Urbana-Champaign. It has been shown in Figure 1. It involves a helicon source along with an Inertial Electrostatic Confinement (IEC) chamber. IEC is a fusion ... En savoir plus

Materials such as aluminium with high thermal and electrical conductivities are of industrial interest, particularly for the automotive industry in the current context of increasing production of electric vehicles. The reflective properties of this material make it difficult to process ... 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

Smouldering is flameless combustion which depends on an exothermic surface reaction occurring within a porous medium. It is harnessed by engineers to destroy organic liquid wastes in soil as the technology Self-sustaining Treatment for Active Remediation (STAR). During this remediation ... 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

In recent years, Atomic Force Microscopy (AFM) has played a key role in the characterisation of surface structures and materials at the microscopic level. One of the most important aspects of AFM image analysis is the reliable provision of pore size and cross-linking rate data. AFM uses ... En savoir plus

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 ...

Microalgae biomass is an essential part of the global ecosystem. Not only is it responsible for 50% of the global oxygen but also proved to be useful in the development of organic polymers, antioxidants, pharmaceuticals, and feedstocks for aquatic animals. It is considered as an ... 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

We present a numerical model for simulating highly nonlinear electrokinetic phenomena, which occurs at high zeta potentials. In this model, the electric double layer is realized by solving a partial differential equation (PDE) on the double-layer-inducing surface. We also allow for a ... En savoir plus
