As the burning of fossil fuels becomes a more pressing issue, manufacturers are introducing more fuel efficient cars to the market. One main contributor to fuel burn is the car’s aerodynamic drag. Complexly shaped, cars are very challenging to model and it’s difficult to quantify the aerodynamic drag computationally. The Ahmed body is a benchmark model widely used in the automotive industry for validating simulation tools. The Ahmed body shape is simple enough to model, while maintaining car-like geometry features.

Behind the wheel of a car is not the ideal place to discover that the steering wheel is defective. That’s why special precautions are taken during the manufacturing process. The carefully controlled cooling of an injection mold ensures that whatever the product may be, its standards are up to par. Here, we use the Non-Isothermal Pipe Flow interface with the Heat Transfer in Solids interface to study the cooling path of an injection mold for a polyurethane car steering wheel.

Try pouring some wine into a glass. Don’t drink it yet — this is a scientific experiment. When you hold up your glass, you’ll see what look like teardrops running down the sides. These tears of wine are caused by the Marangoni effect, which describes a mass transfer along the surface of two fluid phases caused by surface tension gradients along the interface between the two phases (for example liquid and vapor).

Journal bearings are lubricated components that support a rotating shaft. Cavitation affects the performance of these bearings and must be considered during the design stage. Here, I’ll explain what journal bearings are and why predicting cavitation is important, as well as share an industry example with you.

How can you use an electric field to control the movement of electrically neutral particles? This may sound impossible, but in this blog entry, we will see that the phenomenon of dielectrophoresis (DEP) can do the trick. We will learn how DEP can be applied to particle separation and demonstrate a very easy-to-use biomedical simulation app that is created with the Application Builder and run with COMSOL Server™.

We just launched a new app for you to download from the Application Library update. This app is a dedicated tool for modeling the flow and pressure distribution inside a network of connected pipes. Engineers in semiconductor processing could use a tool like this to test a given design and ensure it will meet specification before prototyping the physical device. Here, I’ll give you some background info and walk you through how this app works.
