The generator is low cost, simple to fabricate, and suitable for hydrodynamic quantum analog experiments. We demonstrate the manner in which droplet diameter can be controlled through variation of the piezoelectric driving waveform parameters, outlet pressure, and nozzle diameter.<br>See paper here: &nbsp;<a href=\"http:\/\/math.mit.edu\/~bush\/wordpress\/wp-content\/uploads\/2015\/04\/Harris-DropGenerator.pdf\">Harris, Liu &amp; Bush (2015)<\/a><\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"alignleft size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/thales.mit.edu\/bush\/wp-content\/uploads\/2021\/04\/DropGen3.png\" alt=\"\" class=\"wp-image-6100\" width=\"456\" height=\"306\"\/><figcaption>A millimetric drop from our drop generator is released onto a vibrating liquid bath.<\/figcaption><\/figure><\/div>\n\n\n\n<p class=\"tw-text-wide has-extra-small-font-size wp-block-paragraph\"><br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"tw-text-wide has-small-font-size wp-block-paragraph\"><\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":5,"featured_media":5019,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[13,3],"tags":[],"class_list":["post-3619","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-bouncing-walking","category-pilot-wave-hydrodynamics","entry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v16.3 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Building a better drop generator - John W.
