摘要：
The spraying system is responsible for the particle formation and spray pattern. The most important features of sprays emerging from different atomizers are discussed. In the case of pneumatic atomizers the entrainment is low and a well-mixed jet with little segregation of fine and large particles occurs. A much stronger interaction of gas and spray takes place in the case of large spray angles as, e. g., produced by rotary atomizers. To some extent the particle morphology is known to depend on the drying speed and thus on the entrainment.
