摘要：
Shape selection and dimension design of direct jet spray nozzle are done. Relationship between system pressure p, nozzle inner structure dimension and outer atomization characteristics are analyzed. Simulation results show that the nozzle outlet diameter and system pressure are the crucial two factors for spray atomization. When system flow rate q(v) is 16 mL/r and system pressure p is 14 MPa, the optimal outlet diameter is about 1.5 mm, Trifle fluctuation of outlet diameter may cause great affection to water droplets' Sauter Mean Diameter (SMD) D-32, and 8similar to9 MPa is the baseline of stable atomization pressure. Simulation results are experimentally verified. Besides, nozzle Cylinder length l/d = 2 and pinch angle alpha = 30degrees similar to 60degrees is the best structure to this type of nozzle, jet distance is about 9 m in this condition.
