Phase change materials (PCMs), including shape memory alloys (SMAs), often exhibit thermal hysteresis behavior during phase transitions. Traditional modeling approaches employ binary or threshold-based phase transition models, which is often sufficient for steady-state applications or ... En savoir plus

Voltage sensors are increasingly used for monitoring and load flow distribution. These sensors are safer, lighter in weight and lower in cost as compared to the conventional voltage transformers. The principal component of these sensors is high voltage resistors. The resistors have a ... En savoir plus

Many industrial processes involving chemical reactions rely on heat addition, which accounts for approximately 50% of all energy consumed in the United States' industrial sector. Examples include metallurgical processes, chemical processing, and heating process fluids. Traditionally, ... En savoir plus

The utility company may shut off power in the overhead transmission or distribution lines as a preventative measure against wildfire risks and to ensure public safety. However, the de-energized transmission lines can still carry energy due to induced voltage from the electric- and ... En savoir plus

The increasing demand for electrochemical energy storage (EES) in stationary applications underscores the urgent need for advanced battery technologies. Among these, zinc-based systems, particularly rechargeable zinc-air flow batteries (RZAFBs), are gaining attention due to their ... En savoir plus

This study presents a model for simulating a subsurface pumped-hydro energy storage (battery) system. The model captures the coupling between fluid flow in an oil and gas type wellbore connected to a large hydraulic fracture embedded in a low-permeability reservoir. By integrating ... En savoir plus

The transition to a hydrogen-based, renewable energy economy demands scalable and highly efficient electrolysis technologies. Solid Oxide Electrolysis Cells (SOECs) offer a particularly promising path, outperforming other electrolysis technologies in terms of efficiency and thus ... En savoir plus

We narrow the consideration to HV cylindrical parts, typically with axial leads located on the opposite sides. They are tens of millimeters long, so at moderate frequencies of up to 10MHz they may be analyzed as lumped elements (not as transmission lines), although in some cases they may ... En savoir plus

This study focuses on the time-dependent behavior of moisture and carbon diffusion within the Fumasep FAA-3-30 membrane, utilized in moisture swing Direct Air Capture (DAC) systems. Understanding the concentration distribution of the species within the membrane over time, water flux and ... En savoir plus

Ultrasonic nondestructive testing (NDT) is extensively used in fields like medicine, oil and gas, and aerospace to inspect materials without causing damage. However, developing experimental setups and prototypes can be costly and time-consuming. This study employs advanced computational ... En savoir plus
