Swirl fraction or swirl degree, please help me

Dear all,
I am trying to follow a paper about spray drying and air flow simulation then I am trying to get a same result with the paper. The flow of in a spray dryer is turbulent and two-phase (air and droplet). K-e(realizable and standard wall function) model have been using for turbulence. In the discrete phase model DPM, injection type is a cone, then I defined cone injection with Rosin Rammler distribution method. There is a parameter which is swirl fraction. Do I have to define this? Paper given me swirl degree is 5 degree and water velocity is 49m/s. I little confused with this two parameters. Should i find it? Where i could define swirl degree, what is swirl degree. Is it important?
Thank you so much,
