A Fundamental Classification of Atomization Processes
Abstract
A device-independent framework to classify and describe atomization is developed. This framework divides atomizers into various classes based on the geometry of the liquid prior to breakup. These classes are general enough to encompass the vast majority of existent atomizers while still describing important aspects of the atomization physics. Across these classes a limited number of atomization regimes exist which are grouped based on the magnitude and rate of the atomization processes. Existent literature is reviewed to show how it fits into the current construction of five classes (jet, sheet, film, prompt and blob) and three mode (bulk fluid, mixed and surface). This framework also clarifies the underlying physics of the atomization process. This process consists of the initiation and growth of a disturbance followed by its breakdown. Several categories of disturbance initiation and disturbance breakdown are described supported by examples from the literature.
