Air core reactors are commonly used as shunt reactors, fault current limiting reactors, tuning reactors in capacitor banks. The absence of the iron-core results in a simple and lightweight construction. Consequently, the magnetic field of an air-core reactor is not guided within a ... Per saperne di più
This work presents a small swimmer model in a low Reynolds number ($Re$) environment governed by the equation of motion for Stokes flow in COMSOL Multiphysics®. The entity, a few centimetres helical robot, is located inside of a pipe full of silicone oil, where the forces caused by the ... Per saperne di più
A top-down nanosize mechanical resonator has been fabricated with a shape of a fractal. The self-similar structure consists of star-polygons and it is suspended over a 10 μm trench and has width of 12 μm. Its thickness of 0.040 μm is defined by the fabrication process and prescribes ...

Scanning electrochemical microscopy (SECM) is a technique for recording spatially resolved electrochemical signals. In a typical SECM experiment an ultramicroelectrode (UME) is immersed in an electrolyte over a sample. Additionally, an electrochemically active species called mediator is ... Per saperne di più
Aluminum production potlines operate under significant amperage in a range of 200 kA – 600 kA. High electrical DC currents induce strong magnetic fields. MHD stability, which is a result of electrical current and magnetic field interaction within aluminum reduction cell, is one of highly ... Per saperne di più
This study models the energy harvesting reached from an air flow transportation through the flapping of a cantilever polymer flag. The mechanical resonance of the flag is created by a Venturi channel. The flag is charged by triboelectrification and its flapping between two electrodes ... Per saperne di più
In this work the implementation of an optimization method [1, 2] for inverse heat transfer and for the sensor position correction, such as thermocouples, in COMSOL Multiphysics®and LiveLink™ for MATLAB® is presented. The inverse method is used to determine the unknown boundary condition ... Per saperne di più
The time-dependent operation of methanol, ammonia, and urea production units embedded in a steel mill technical environment is analyzed with dynamic simulation models. From different process concepts and gas availability scenarios a set of simulation cases is defined with blast furnace ... Per saperne di più
Finite element modelling of surgical transducers has been performed and is described. Ultrasonic transducers vibrating at around 25 kHz are used in orthopaedic surgery to cut bone. The high acoustic impedance of the metal blades used in these devices couples energy more efficiently to ... Per saperne di più
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 ... Per saperne di più
