liquid injectors(pressure swirl atomizer)

(OP)
hi
i wont to design a pressure swirl atomizer for a turbofan engine but i don't know the recommended valus of some parameters to start my design.
such that(injector pressure differential,ratio of nozzel length to its diameter,cross sec area of nozzel,fuel mass flow rate)
if there is another parameters must be assumed before design please tell me about it
how can i evaluate the fuel size distripution without needing exprements(we have no lap)
note: iam not (agricultural) but i don't know how to chamge it (iam a new user tell me how)

thanks for any help  

RE: liquid injectors(pressure swirl atomizer)

I've got a MathCAD file that inputs port area, radius of swirl generator, radius of orifice, fluid density, differential pressure & an experimental correction factor and mass flow rate and cone angle.  I don't know how to post it & I can't just cut & paste it here as it is full of special characters.  Won't do you any good if you don't have MathCAD anyway.
