Investigation of Turbulence Boundary Condition

The effect of turbulence boundary condition is examined. The following three plots illustrate the result.  

 Figure 1: Turbulent intensity 10% Turbulent length scale 0.004 (BL thickness * 0.4) 

Figure 2: Turbulent intensity 1% Turbulent length scale 0.04

Figure 3: Turbulent Intensity 20% Turbulent length scale 0.0004 

Comparing figure 1, 2 and 3, big changes of turbulence boundary conditions did not affect the solution much. We just need to do rough calculations on the parameters to input for accurate result. Final boundary condition is the Turbulent intensity of 10% and turbulent length scale of 0.004
