Atomization Characteristics of Spray-to-Spray Impinging Atomizer.
Journal of the Japan Institute of Energy, 1999 The atomization characteristics of spray-to-spray impingement system was investigated in this study for the purpose of its prospective utilization in continuous combustion burners which are used for boilers etc. Two twin-fluid atomizers were used as impinging spray. The total spray quantity is 35 1/h at maximum.
