ing of liquids and slurries. Annual technical conferences are organized by each of the ILASS organizations ILASS-Americas, ILASS-Asia, and ILASS-Europe. ILASS-International is an overarching coordinating board made up of representatives from the three regional ILASS Institutes. ILASS meetings have practitioner and researchers from many areas where spray technology is utilized. This includes injectors for

gas turbine A gas turbine, also called a combustion turbine, is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the directio ...

s, rockets, and diesels, agricultural and medical sprays, industrial sprays, fire protection, paint and coating applications, and many others. This breadth of spray applications at this conference and technical community provides cross-fertilization of research methodologies and innovative efforts. Mechanical, agricultural and chemical engineers all participate in these meetings. The community embraces the synergy of experimental, theoretical and computational models to advance the technology and science. Presentations include experimental evaluation of spray systems and

spray nozzle A spray nozzle is a device that facilitates the dispersion of a liquid by the formation of a spray. The production of a spray requires the fragmentation of liquid structures, such as liquid sheets or ligaments, into droplets, often by using ki ...
