  • Malvern laser particle analyzer was used to study the atomization characteristics along the axial direction of fuel injector and cavity-based strut flame stabilizer under close-range matching condition, with stream Mach number of 0.16 to 0.24, spray pressure drop of 0.30MPa to 0.90MPa, distance of fuel injector and stabilizer up to 31.5mm and spray in the direction of stream flow with water and kerosene. The results show that the Sauter mean diameter(SMD) of liquid drop decreases with increasing stream Mach number and increasing spary pressure drop. But the SMD of liquid drop was not sensitive to spray pressure drop in recirculation zone and to Mach number in main stream zone at the far-field downstream position of cavity-based strut flame stabilizer. Furthermore, the SMD of liquid drop decreases gradually along the axial direction, and decreases gradually in recirculation zone but increased gradually in main stream zone along the radical direction.
