Article on BBC Science Focus about Iron Man and Non-Spherical Particles

Most of the time my fundamental research at TU Delft and my superhero work walk side by side with no obvious overlap between the two topics. However, earlier this year, one of the PhD students in our group published a very nice paper about drag forces experienced by non-spherical particles in fluid flows. In the paper, they found that the drag force experienced by a particle in the flow could be calculated for any orientation of the particle provided you know the drag force when the particle is parallel to the flow and perpendicular to the flow.

Now like many science papers it is very technical but with some very nice illustrations and diagrams. After I read the paper I got the idea to write a popular science article about the work and link it to the drag forces that Iron Man might experience. When Tony Stark is in the suit he sort of looks like a non-spherical particle in a way.

The article was published last week on BBC Science Focus Online magazine and can be read here. The article has even shared the front page for some time with an article about Stephen Hawking. You can see this in the image below with my article on the bottom right of the image.

Stay tuned as I've another article in the pipeline.
