This paper describes how to numerically tackle the problem of counting and sizing particles by impedance measurement in an orifice–electrode system. The model simulate the particle dynamics submitted to strong hydrodynamic stresses through a microorifice and compute the voltage pulses ... Mehr lesen
Single coil actuators are representing one important component of ABB’s medium voltage reclosers. Their performance is strongly influenced by the considered material properties as well as by the electronic control units’ properties that will power the actuator. Therefore, this paper ... Mehr lesen
Fuel bundles in the CANDU (CANada Deuterium Uranium) reactor are designed for heating a pressurized coolant (heavy water) to generate electricity. The designs for the fuel bundles differ based on the number of heating elements. The flow of heavy water over the elements and inside the ... Mehr lesen
An alluvial aquifer system has probably conceived as a numerical modeling hell. We have chosen COMSOL Multiphysics® for two reasons: 1) FEM methods allow to use complex geometries; 2) multiphysics simulation permits to run a single model with all phenomena. We built a section with these ... Mehr lesen
Noninvasive radiofrequency (RF) tissue heating is frequently used for skin tightening and facial wrinkle reduction as alternative to invasive surgical procedures. However, to ensure a safe and efficient therapy, the temperature of the skin and the subcutaneous tissue must be controlled ... Mehr lesen
The optimisation of dimensions, materials choice of heaters in annealing furnaces are done with COMSOL Multiphysics® in 2D-axisymetry. Heat losses sources are identified and corrective actions can be taken in function of simulation results. A power saving of more than 50% is achieved ... Mehr lesen
Micro-tubular Solid Oxide Fuel Cells (mSOFC) are attracting more and more interest as new generation of energy conversion devices. Although commercial applications still suffer from high costs, there is a need for further improvement of the cell performance, durability and start-up. To ... Mehr lesen
Recovery of oil by gas injection is usually inefficient due to the low viscosity of the gas, which results in bypassing of the oil. By adding surfactant solutions it is possible to get in-situ foam formation. Foam has a much higher “viscosity” and hence does not bypass the oil, leading ... Mehr lesen
Besides conventional laboratory analysis methods, so called micro-total-analysis devices (µTAS) have gained great interest during the last decades. In this work we demonstrate a mechanism for the separation and selection of medical samples that can be applied within these µTAS devices. ... Mehr lesen
The electrochemical pickling of steel has two main purposes: 1) To remove thermal oxide; 2) To dissolve chromium-depleted layer, to reinstate the corrosion-resistant properties of the stainless steel; A reliable, flexible and robust 3D model has been made for simulating the steel ... Mehr lesen
