Pressure distribution on a wing
Another neat experiment in the collection I’ve recently been talking about is measuring pressure at different points on a wing profile. It’s not terribly surprising that – as long as…

Pitot tube
Another one of those awesome hydrodynamics toys: A Pitot tube! This is what it looks like: What you can’t see here is the little hole at the tip of the…
Playing with Venturi tubes II
On Monday I posted about playing with Venturi tubes. Guess what: We are going to play more today! Because today the Venturi tubes are connected to a “proper” manometer: Now,…
Playing with Venturi tubes
A Venturi tube is one of the things one hears about in hydrodynamics class all the time, but one never gets to see them for real. And even though I…
Flow direction reversing downstream of obstacle
One of the things that fascinated me most when playing with the huge fan we used to look at the flow downstream of a paddle was how the flow direction reverses.…
Flow around obstacles
We’ve played with the flow around a paddle recently, and you didn’t really believe I stopped there, did you? Of course I didn’t! But I have many many hours of…
Visualizing flow around a paddle
Whenever I’m in a canoe or kayak, I love watching the two eddies that form behind the paddle when you pull it through the water. It looks kinda like this:…
Ball balancing on air flow
Recently, someone at my university told me about a case of experiments connected to aerodynamics* that they occasionally use for demonstrations and outreach. Obviously, I asked if I might possibly…
