      I am working on a Fluent model of turbulent flow in a pipe. Data for the model follows:

      0.2 m diameter, 20 m length

      water fluid

      inlet velocity: 0.1 m/s

      outlet pressure: 0 Pa

      Axisymmetric Geometry with 500 x 30 graded mesh

      k-epsilon model

      I have attached plots reflecting

      Reran case with "Enhanced Wall Function" and the results are now very close to the analytical solution. Sorry for bothering the forum as I found a helpful discussion related to this from May 2020.
