Liquid sprays are formed through the process of atomization, where a liquid jet is passed through a nozzle, resulting in a fine spray. This technology has various applications, particularly in diesel engines. The discussion highlights the need for more specific information and resources on liquid atomization and fluid dynamics related to liquid sprays. Participants share links to relevant articles and textbooks, such as "Industrial Sprays and Atomization" by G.G. Nasr, and express a desire for clarity and structured inquiries. The conversation also addresses concerns about potential spam and encourages proper forum etiquette for effective communication.
