Electrothermal actuators convert an electrical signal into a mechanical signal via Joule heating. Due to their simplicity and reliability, electrothermal actuators are commonly used in various fields across length scales: from human-scale soft robotics to nanometer-scale sensors. We ... Read More

A pneumonectomy is an invasive, high-risk surgical procedure performed to remove the right or left lung. Although this may be a life saving procedure for some patients, it has high morbidity rates and many complications post-pneumonectomy. Pneumonectomies result in the heart’s entire ... Read More

Introduction: Modeling biological structures is challenging due to their often complex anatomical geometries and material properties. Finite element studies of the femur, the largest and strongest bone in the human body, have focused on the femoral neck, since this is where fractures ... Read More

Sustainable wastewater management has stimulated the exploration of innovative technologies, such as electrochemical nutrient recovery, which promises efficient recovery and reuse of vital nutrients, reducing environmental impacts and resource wastage. This study presents the modeling of ... Read More

Convection is a method of heat transfer which takes advantage of a fluid’s flow over a solid. At this boundary between the solid and fluid, the convection is quantified by the convective coefficient (h) and the following boundary condition is implemented: [9] k∇T=h∆T where h is the ... Read More

It is common knowledge to readers of these COMSOL conference proceedings that COMSOL (as well as other established CFD codes) produces unstable numerical solutions of the Navier-Stokes equations without "consistent stabilization" and/or "inconsistent stabilization" (or similar ... Read More

Introduction Wind presence in extreme cold temperatures is an accelerator of frostbite in susceptible areas. The National Weather Service (NWS) Wind Chill Temperature Index (WCTI) accounts for exposure time to frostbite in the cheek based on simplified human thermoregulatory models ... Read More

Introduction: The endothelial cells (ECs) in the blood brain barrier (BBB) are disrupted with age, genetic predisposition, or stroke and can lead to vascular cognitive impairment and dementia (VCID). Current treatments involve opening the BBB with high-frequency-ultrasound to deliver ... Read More

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 ... Read More

Excessive vent noise poses a prevalent challenge in various acoustic applications, significantly impacting the performance and user satisfaction of audio systems. This research investigates the efficacy of noise reduction using a lumped speaker model implemented in COMSOL Multiphysics. ... Read More
