Turbulent Pipe Flow
Created using ANSYS 13.0
Problem Specification
Let's revisit the pipe flow example considered in the previous exercise. As before, the inlet velocity is 1 m/s, the fluid exhausts into the ambient atmosphere and density is 1 kg/m3. For µ = 2 x 10 -5 kg/(ms), the Reynolds no. based on the pipe diameter and average velocity at the inlet is
