Portable Cordless Vaccine Storage Device
The Passive Vaccine Storage Device (PVSD) is a highly advanced container that combines ingenuity and insulation technology to empower aid workers delivering vaccines to the toughest-to-reach corners of the globe. Designed as a prototype that improves upon earlier models of vaccine transportation devices, this compact apparatus was developed with all the necessary steps: careful planning, simulation, and testing.
Video Tutorial: Capacitive Pressure Sensor
If you are searching for a tutorial on how to model a miniaturized 3D electromechanics problem, then look no further. We have just published an updated version of our video tutorial on how to simulate a capacitive pressure sensor. COMSOL Multiphysics version 4.4 and the MEMS Module are used to simulate the electrostatic, structural, and thermal physics that occur.
Air Pressure Sensor Performance Relies on a Solid Design
With all of the other components of an automobile to consider, it is easy for drivers to forget to routinely check tire pressure. Thankfully, companies are actually beginning to assemble most of their newer vehicles with built-in tire pressure monitoring sensors. These devices are placed at the bottom of the tire hub and measure air pressure automatically — all while the car is still in motion.
Improving Your Golf Swing with a Multibody Analysis
How well you can strike a golf ball is not only determined by your muscle strength, but more importantly — it is influenced by several other factors involved in the mechanics of your golf swing. Let’s see how a multibody analysis of a golf swing can be used to improve the outcome of your stroke.
How to Model Residual Stresses Using COMSOL Multiphysics
Today, we will introduce the concept of residual stresses in structural mechanics and find out how to compute them by taking the example of a deep metal drawing process. First, we will explain how they can be computed and interpreted in a bending beam example with or without work hardening. Then, we will introduce a sheet metal forming model.
Cable Simulations Spark New Developments at Prysmian Group
Energy and telecom cables often journey through harsh environments to reach their destinations. Some cables are responsible for carrying high currents and must navigate in conditions that include high thermal loads, mechanical loads, and limited ventilation. We recently published a story in the IEEE Spectrum Insert, Multiphysics Simulation, explaining how the Prysmian Group, a leader in developing cable systems across many industries, has begun using COMSOL Multiphysics to improve their development process, save resources, and optimize their cable designs.
Heat Transfer in Deformed Solids
In a previous blog post, we presented the applications of conjugate heat transfer involving immobile solids. The case of immobile solids simplifies the heat equation to be solved and is often a good approximation to the temperature field. Today, we will complete the description of the physics that account for thermoelastic effects of the material when heat transfer and solid mechanics are coupled.
Hyperthermic Oncology: Hyperthermia for Cancer Treatment
High temperatures can be used to destroy tumor cells, a cancer treatment known as hyperthermic oncology. Although the idea behind this treatment method has been around for some time, it wasn’t until recently that new tools and more precise delivery of heat has allowed hyperthermia to be used for cancer treatment. As hyperthermic oncology studies continue, simulation has proven a valuable tool for achieving a deeper understanding of how to deliver heat to tumors while limiting damage to healthy tissue.
