| Abstract: | Design parameters of the atomizing nozzle with ring holes is qualitatively explained and quantitatively described based on the theory of atomizing jet flow.The mathematical expression of the atomization pressure required for maximum jet velocity has been presented,and the relationship of the exit area and the atomizing chamber area required for producing maximum exit jet velocity and maximum gas mass flow rate have been established.The influence of jet apex angle,jet distance,pitch circld diameters and the ... |
