The Institute for Liquid Atomization and Spray Systems, (ILASS), is an organization of researchers, industrial practitioners and students engaged in professional activities connected with the spray
Spray can refer to:* Spray ** Aerosol spray** Blood spray** Road/tire spray, kicked up from a vehicle tire** Snow spray, a spray that creates artificial snow fall...

ing of liquids and slurries. Annual technical conferences are organized by each of the ILASS organizations America, Asia, and Europe. ILASS international is an overarching coordinating board made up of representatives from the three regional ILASS groups.

ILASS meetings have practitioner and researchers from many areas where spray technology is utilized. This includes injectors for gas turbine
Gas turbine
A gas turbine, also called a combustion turbine, is a type of internal combustion engine. It has an upstream rotating compressor coupled to a downstream turbine, and a combustion chamber in-between....

s, rockets, and diesels and agricultural 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 this meeting.

This 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
Spray nozzle
A spray nozzle is a precision device that facilitates dispersion of liquid into a spray. Nozzles are used for three purposes: to distribute a liquid over an area, to increase liquid surface area, and create impact force on a solid surface...

s under a variety of applications. Recent advances in instrumentation for drop size, drop velocity, and quantified spray pattern continue to result in advances in the state-of-the-art. In addition, film thickness and fuel vapor are important parameters in many applications.
