Designing Electric Vehicles with Magnetic Cooling Technology
In a previous blog post, we focused on the growing use of magnetic cooling technology as a safer, more eco-friendly method of refrigeration. Here, we look at how one team of researchers analyzed the potential use of this technology in the design of electric vehicles.
Accounting for Heat in the Design of Lithium-Ion Batteries
In the performance of lithium-ion batteries, thermal management is an important element to consider. Through modeling and simulation, you can improve the design process by analyzing how heat is transferred within the energy source.
Improving the Beer Brewing Process with Simulation
There are two aspects of home brewing: the culinary side and the engineering one. Many beer lovers start brewing either to improve a recipe, try to clone their favorite beer, or even simply just to see how it works. After brewing a few batches, however, it turns out that the brewing process can also be very challenging from an engineering point of view.
Modeling a Coil Heat Exchanger
Coil heat exchangers are simple and easy to manufacture. Here, we consider an axially wound coil of copper carrying hot water that heats air inside of a circular duct. Since the geometry is almost invariant about the centerline, the model is solved in the 2D axisymmetric plane. Additional expressions are added to compute the temperature drop between turns of the coil, which greatly simplifies the modeling.
Phase Change: Cooling and Solidification of Metal
Modeling phase change is important for many thermal processes, ranging from the food industry to the metal processing industry. The Heat Transfer Module offers a dedicated interface for modeling the characteristics of phase change. It uses the apparent heat capacity method, which we introduce here.
Optimizing the Continuous Casting Process with Simulation
The Swiss steel company SMS Concast has been leveraging multiphysics simulation to optimize the steelmaking process of continuous casting. Through research conducted using COMSOL Multiphysics, the R&D team at SMS Concast was able to implement a new technique that allowed a steelmaking plant in Taiwan to reduce yearly CO2 emissions by about 40,000 tons.
Designing Fully Superconducting Rotating Machines
Imagine a mode of air travel that is both fuel efficient and environmentally friendly. The mechanical modeling of torque transfer components in fully superconducting rotating machines have helped researchers draw new conclusions on how to optimize aircraft design and potentially achieve electric propulsion. A research team investigated the stress and heat distribution in these machines and presented their results at the COMSOL Conference 2013 in Boston.
A Recipe for Success at Whirlpool Corporation
There are many factors that go into designing the ideal oven — supreme cooking capability is a must, but energy efficiency and the use of materials with reduced environmental impact is also important. How can all of these different factors be combined to create an oven that is optimized for the best performance? Engineers working at Whirlpool Corporation along with the European green energy initiative, GREENKITCHEN project, found that multiphysics simulation was vital to the success of their design process.
