Multiphysics Method for Short Circuit Stress Calculation in Power Transformer
The aim of this work is to compute the mechanical stresses in power transformer winding due to an external short-circuit event. This event can be considered as one of the most demanding load conditions and many details such as material type, type of constraints, winding geometry ... Mehr lesen
Experimental Validation of a Multidimensional Model for an Indirect Temperature Swing Adsorption Unit
Temperature Swing Adsorption (TSA) processes are applied for the removal of impurities from various gas streams. The limiting factor of a TSA process is the regeneration step, which is characterized by long heating and cooling times. To reduce the regeneration time, indirectly heated and ... Mehr lesen
Measurement and FEA Simulation of the Electro-mechanical and Acoustic Response of an Of-the-shelf Open-type Piezoelectric Flexural Ultrasonic Transducer
High power, air-coupled ultrasound has gained significant interest from the research community due to the rise in applications such as non-contact particle manipulation, haptic feedback, and sound steering. A growing number of researchers are utilizing transducers designed for proximity ... Mehr lesen
Numerical Investigation of Micro Droplet Contact Angle Hysteresis on a Heterogeneous Solid Surface: Application to Carbonate
Contact angle hysteresis is an important physical phenomenon, it is an essential parameter in wetting and capillarity, and it plays an important role in many industrial processes, especially in Enhanced Oil recovery (EOR). In this paper, the contact angle hysteresis (CAH) of ... Mehr lesen
Simulation of Bi-Material Nano-Second Laser Ablation
In the field of laser applications, surface treatment is highly studied. Two process categories are commonly used. First processes use very short pulses (femto or pico seconds) known to avoid thermal effects and to have high spatial resolutions. Second processes have higher interaction ... Mehr lesen
Geophysical Fluid Dynamics: Modelling Non-Linearly Viscous Ice-Flow to Obtain Dates of Flow Change
Ice flows because at low stresses it deforms viscously; the viscosity depends upon the stress. The lubrication approximation (LA) states shear stress is proportional to the product of the ice depth and surface slope. At ice divides the slope and shear stress are zero meaning the ... Mehr lesen
High-Resolution CFD Modeling of a Large-Scale Short-Term Thermal Energy Storage Unit
Small-scale short-term thermal energy storage (TES) systems and large-scale seasonal TES systems have been the focus of many research projects. However, large-scale short-term TES units have not been covered in great depth, even though they play an important role by decoupling the heat ... Mehr lesen

In this work, we present a methodology for the design and analysis of a double-sided linear induction motor for a scaled Hyperloop pod in COMSOL Multiphysics®. The key aspects are discussed as follows: Formulation of problem and simulation environment: The goal is to design a Double ... Mehr lesen
Predicting the Fate of Contaminant and Remediating Nano-Particles in a Polluted Aquifer with an Integrated Modeling Approach
The presence of anthropogenic or natural pollutants in groundwater system poses a threat to water resources. Several remediation techniques have been explored and developed to decrease the concentration of contaminants. One such remediation technique, injection of nano-particles in the ... Mehr lesen
Thin Microchip Release From a Carrier Tape: Structural Mechanics and Vacuum Forces
During semiconductor manufacturing, finished silicon microchips need to be released from a carrier tape they stick to by an adhesive. This is done by vacuum forces that (a) hold the chip flat from above and (b) pull the tape off from the chip underside. Sounds simple, but is very tricky ... Mehr lesen
