Did you know that thermal management of a cylinder head had started way before it was bolted on your engine block? It was the single most important 90 minutes of its service life. It first happened when the cylinder head casting emerged from the die freshly cast, still liquid behind the thin solid outer layer of aluminium. This article tells how Computational Fluid Dynamics plays a defining part o...

In 2012 we received an interesting fluid flow and heat transfer simulation job. A silencer had to be installed on a carbon-dioxide exhaust point of a huge chemical factory. Within this project our job was to carry out a CO2 diffusion CFD analysis in the atmosphere of the ammonia works. A chemical factory CFD analysis is complex by its own right but as a bonus how can the area of a whole production...

I had the chance some weeks ago to spend a day at the site of one of our SC/Tetra users. They showed me a small mixer in their lab on which they make some demonstrations and test measurements for their students. They also created a CFD simulation to model the mixing process. And because it was so interesting, I decided to build a free fluid surface CFD simulation with an other mixer geometry. The ...

This information video shows CFD modelling of an interesting physical phenomenon. Pressure wave CFD simulation is used on a test pipe to demonstrate wave propagation in pipes. This phenomenon is also called the water hammer effect. There are two examples shown in the video. The first is a simple pipe, the second one is a bit more complex because there are junctions in the pipeline. Pipe geometry h...
