Figure 2 shows the meshing parameters that were used. The boundary layers was first establish established at all the wall surfaces. The boundary layer was set up such that the solution obtain in gambit would provide a result of y+ of less than 5. After that, the mesh edges were set up such that they will provide higher mesh resolution near the turn and lower resolution far from the turn. With the initial meshing conditions set up, all the faces were then meshed.
