Submicron droplet formation in the human lung
Web1 May 2024 · Respiratory droplets are generated through typical human exhalation activities, such as breathing, speaking, coughing and sneezing (Chao et al., 2009; Tellier, 2006). Many of these droplets evaporate rapidly to half of their original size before reaching equilibrium with the ambient relative humidity. Web14 Feb 2024 · An in-depth review on a new ultrasonic micro-droplet generator which utilizes megahertz (MHz) Faraday waves excited by silicon-based multiple Fourier horn ultrasonic nozzles (MFHUNs) and its potential applications is presented. The new droplet generator has demonstrated capability for producing micro droplets of controllable size and size …
