I’ve decided it’s time to consolidate my blogs into one magnificent blog! Seriously, you’ll find posts about fluid dynamics at this new url, along with all of the existing posts, and posts about other topics as well. How can you find the fluid mechanics posts? Just click on FLUIDS in the Categories list in the sidebar. You’ll also know a fluid dynamics post when you see one because of the featured image. I hope to see you there!
Coming soon – an interview with Brad Gemmell – a researcher who discovered the secret to the propulsive power of jellyfish!
This video does an outstanding job of making the Reynolds Number meaningful. More about the use of the Reynolds Number in scale model testing in future posts!
Most of us have observed jellyfish in action at one time or another. In my experience, I have watched them as they surrounded the small boat I was on, on a sunny summer day with no way to swim until they’d made their way past. I’ve also watched them in an exhibition at the National Aquarium in Baltimore. From the vantage point there, I was able to see the portions of the jellyfish that were below the waterline. It was a beautiful site. Continue reading
In this BBC presentation, Physicist Dr Helen Czerski takes us on an amazing journey into the science of bubbles. Bubbles may seem to be just fun toys, but they are also powerful tools that push back the boundaries of science. From the way animals behave to the way drinks taste, Dr Czerski shows how bubbles affect our world in all sorts of unexpected ways. Whether it’s the future of ship design or innovative new forms of medical treatment, bubbles play a vital role.
It’s a long video, but well worth the time. Pop your self some popcorn. Grab a bottle of water. Settle back to be enthralled by —— bubbles
One of the most impressive things about penguins – and puffins – is the way they rocket out of the water to land on the ice. Not only do they stick the landing, they come out of the water with enough momentum to gain a foothold.
In this video, Helen Czerski – physicist and oceanographer based at the Institute for Sound and Vibration Research at the University of Southampton – explains the role that fluid dynamic principles play in this amazing penguin ability.
