Finite element modeling of three-phase induction machines requires the solution of coupled circuit and field equations. This work aims to solve this problem using a strong coupling approach. This work includes circuit field coupling and proper air-gap meshing, using the AC/DC Module of ... En savoir plus

Working on Faraday’s law of electromagnetic induction, electromagnetic flowmeters measure flowrate on the basis of the electric potential induced when a magnetic flux interacts with flowing water. The electromagnetic coils of the flowmeter are crucial to its operation, given that the ... En savoir plus

Micromachined ultrasound transducers can work as a sensor or actuator for measuring fluid speed and direction, mixing and exciting particles (sonication), taking images (ultrasonography), non-destructive testing and many other purposes in various fields. In this work, a COMSOL ... En savoir plus

The authors present a closer look on the Single-Well Injection-Withdrawal Experiment (SWIW) or Push-Pull Experiments and its ability to determine the groundwater velocity, as one of the major parameters concerning reservoir management and underground reservoir characterization. The flow ... En savoir plus

Drilling horizontal wells (HWs) has recently received renewed attentions with the increasing trend in exploitation of tight gas reservoirs. An accurate estimation of productivity of such systems using a numerical simulator is a challenging task, because its 3D simulation requires a fine ... En savoir plus

Modern composite membranes for reverse osmosis (RO) and nanofiltration (NF) have an ultrathin polyamide active layer (~100 nm) that performs the ion separation. Current theoretical models explain solute and water fluxes by computing concentration and potential gradients developed in one ... En savoir plus

Electrochemical Machining (ECM) is a non-conventional machining technology which allows for surface structuring and shaping of metallic workpieces with high accuracy and surface quality. The machining principle of ECM is electrolysis. Hence, the mechanical properties of the workpiece ... En savoir plus

Very recently, the synthesis and experimental study of a new class of highly charged polymer particles has been described, which spontaneously charge in non-aqueous low-polarity solvents [1,2]. These suspensions are an example of what is known as salt-free systems. The study of ... En savoir plus

Introduction Throughout the field of micro- and nanoscale electrokinetics, floating bipolar electrodes (BPEs) have proven to be useful in manipulating charged ionic species and biomolecules for electroanalytical studies. The growing use of integrated electronics in working towards fully ... En savoir plus
