Spray drying gradient, concentration

Evaporation of Atomized Droplets. The prediction of the time to totally evaporate a liquid droplet in an atomized spray is very difficult due to the complex thermal and concentration gradients present in the vicinity of the nozzle. Despite this complexity, it will be beneficial to study what happens to a single droplet of liquid when it is surrounded by a quiescent gas stream. This phenomena has been studied extensively because the time to evaporate a liquid drop has important consequences in a number of different applications e.g., spray drying, fuel injection, and coating.
