The aeroacoustics of a steam kettle.

Researchers have finally worked out where the noise that makes kettles whistle actually comes from – a problem which has puzzled scientists for more than 100 years.

A basic kettle whistle consists of two plates, positioned close together, forming a cavity. Both plates have a hole in the middle, which allows steam to pass through.

Although the sound of a kettle is understood to be caused by vibrations made by the build-up of steam trying to escape, scientists have been trying for decades to understand what it is about this process that makes sound.

SICB DCB and DVM Southwest Regional meeting at UCR today. Heard some wonderful talks (excited that Dr. Clark is coming to CSUSB to talk about hummingbird aeroacoustics in November!), had free lunch (Thai food!) and dinner (hotdogs at DDogs!), and spent time with some wonderful people.
