testing case for wastewater in a circular pipeline
 

i have been looking for a testing and validating case for wastewater flow in a circular pipe. but i just cant find any. i just need to start the testing of my model with a simple case, let say 2D, laminar, steady state or a case with a higher complexity but yet somehow simple one. can any one help me in this regard

thank you in advance

forgot to mention that i'm very new to CFD, and i just started learning and using CFX before one month and i built my pipe model of wastewater pipe but i need to go through the experience of testing and validation!!
one thing i noticed about most of the online databases that they are really old dated!! most are before 2005!!!
