Application of ULDF to determine maximum drop size produced by pneumatic atomiser / Fauziah Jerai@Junaidi and Ow Chee Sheng

Pneumatic atomisers are well suited to the production of sprays with average drop diameter less than 30fim mass mean diameter depending on the pressure used. The maximum size of the drops formed are a function of the design of the atomiser. In this study, droplet size in a pneumatic atomiser was mea...
