Performance parameters analysis in 2D - sensitivity analysis: convergence level and boundary condition at the water-air interface

Objective

The preliminary simulation experiments suggested that the results are sensitive to the residual levels the solutions converged to and the boundary conditions defined at the water-air interface. A more detailed sensitivity analysis is discussed in this section to exam the accuracy and validity of the results obtained in the simulation experiments section, with respect to the above two conditions.

An h/b ratio=5 was chosen for both the cases with symmetry(frictionless) and wall(no slip)boundary condition defined at the water-air interface. The solution data were saved for both simulations cases at the residual levels of e-4, e-5 and e-6 were saved and the respondant performance parameters were calculated. (Refer to Method and Procedures sections of either simulation experiments section or preliminary simulation experiments section for the creation of geometries and meshes, and the report summaries about all FLUENT settings).
