Abstract
The invention relates to a method and device for generating drops or bubbles in liquids with a range of sizes which, under normal pressure and temperature conditions, can vary from hundreds of micrometres to several millimetres. When the liquid or gas to be dispersed is passed through small holes which open into a transverse current, menisci are formed, from which small drops or bubbles emanate. The fraction of energy used in the process, which takes the form of an increase in the surface of the liquid/liquid or liquid/gas interfaces, must be maximised in relation to the energy transferred to the system in order to render the generation of drops or bubbles as efficient as possible. The device can be used in the fields of oxygenation and aeration of liquids, chemical engineering and food technology.
