Magneto-Hydrodynamic (MHD) power generation systems were originally investigated starting from the fact that the interaction of a plasma with a magnetic field must take place at much higher temperatures than could be observed in a mechanical turbine. The main problems of traditional MHD ... En savoir plus

Convective instability in a thin liquid layer is observed in many technical systems [1] and is of interest to the self-organization theory. To date, however, only simple problems with the convection between flat plates are well studied [2]. In real systems and devices, convective flows ... En savoir plus

Electron beam welding process is a high-energy welding technique that uses a focused beam of electrons to join metal components. It is widely used in various industries, including aerospace, nuclear industry, automotive, and electronics, due to its ability to produce high-quality welds ... En savoir plus

Process Hardware for heating, etching and plasma deposition in vacuum processes on Silicon wafers or glass substrates face challenging requirements due to very shallow and extended structures. Molecular Flow calculations are used to evaluate staggered shields with the aim to protect ... En savoir plus

Laser additive manufacturing has become an interesting field of engineering which is revolutionizing industrial processes. Selective Laser melting (SLM) is a widely used additive manufacturing technique for 3D printing of metal structures. This process has a particular complexity in ... En savoir plus

It has already been demonstrated that fluid models can be used to simulate two-dimensional axisymmetric inductively coupled plasma via implementation in the COMSOL (multi-physics simulation software) platform. In this study, we improved the model and simulated a large scale magnetized ... En savoir plus

Particle velocimetry using image analysis is an effective non-intrusive method used for fluid velocity field estimation in micro-channels. We use COMSOL with MATLAB to generate velocity fields for micro-channel designs and then calculate changes in particle position for given imaging ... En savoir plus

The interaction of high power laser beam with metallic materials produces a number of interconnected phenomena that represent a serious challenge for numerical modeling, especially for creation of auto-consistent models. Additional difficulty consists in lack of data on materials ... En savoir plus

Single droplet drying (SDD) is an established experimental set up in which an isolated droplet is dried under a controlled environment. The drying behavior in the SDD experiments is often complicated and challenged to observe. Hence, a robust model of single droplet drying can provide an ... En savoir plus

In this work, we present simulations of a novel micromachined calorimetric flow sensor using COMSOL Multiphysics. The sensor is based on four germanium thermistors that serve as heat sources and as temperature sensors simultaneously. In operational mode, the heated membrane is cooled by ... En savoir plus
