I intend*to find a method by which I can understand the onset of different flow patters (i.e. annular, rimming, pool .etc) by varying the liquid fill percentage and/or the rotational velocity of the cylinder. I want to find out such data for a variety of setups and hence am not using CFD or experimentation. It would be of great help if anyone could suggest a source to find the same.

Hard to imagine what other source you envisage for material, but Philip Ball's book has some ideas from revolving cement mixer drums to more fluid fluids.
