Hi,
i am dealing with with super-critical water flowing vertically upward in a circular tube. I am getting my best results at y+ value above 300 which means that i am unable to get the wall effects as i am using k-e, RNG with enhanced wall effects so theoretically it should give me the results at Y+ value between 1 to 5 but not in my case as stated earlier. I am much confused what does it mean and how to explain the physics of results i am getting at y+>=300.
please help me out

Best Regards
