A short circuit in a battery is bad news: the chemical energy stored in the battery is lost as heat, rather than being used to power a device. Short circuits create intense heat, which can degrade battery materials or lead to fires or explosions due to thermal runaway. To avoid conditions that lead to short circuits in devices and ensure that short circuits do not cause unsafe operating conditions, we can study lithium-ion battery designs with the COMSOL Multiphysics® software.

When studying a system’s chemical kinetics, it’s common to use perfectly mixed batch reactor assumptions and design experiments that keep mixing conditions ideal. Such assumptions include perfectly mixed (ideal tank reactors) and perfectly unmixed (ideal plug flow reactors). In reality, however, it’s rare that all of the reactor’s parts behave the same way. Space-dependent modeling is thus essential in understanding and optimizing chemical reactors. Let’s explore the development of a detailed reactor model, starting with a simple perfectly mixed example.

You might think you’re a smooth driver — but your engine probably doesn’t. Everyday obstructions like traffic lights and changing speed limits mean that the power demands of a car drivetrain vary rapidly. Since we expect new technologies like hybrid or electric vehicles to match the performance of existing cars in responding instantly to the demands of our right foot, designers need to make sure that this is possible and safe. One part of this involves modeling batteries.

Architects cannot just be artists. A new building must not only be aesthetically pleasing but also structurally sound. In the design of modern buildings, great attention is paid to concepts such as environmental comfort and energy efficiency. With a range of physical problems to address in the transition from a building’s concept to a completed design, the 21st century architect may turn to multiphysics software.
