Whistle while you work
Computational fluid dynamics was never my forte but I make a mean cup of tea. A
team at the University of Cambridge have addressed an issue that
thwarted acoustic scientists for years, namely how does a kettle whistle?
Apparently the answer lies in pressure pulses that form steam vortices that
produce sound. I wonder Oolong the research took?
