APPENDIX 1 : SMARTFIRE VERIFICATION AND VALIDATION REPORT2.3 Symmetry boundary condition testThis case is intended to test if the symmetry function works correctly. The case involvesflow expansion from a small duct into a larger duct. The configuration is shown in Figure 7below. The case was simulated using the whole flow domain and then repeated using asymmetry boundary condition along the central axis.Figure 7 - Expanding duct with symmetry line indicated2.3.1 SMARTFIRE resultsThe flow fields of the symmetry case (Figure 8) and whole field case (Figure 9) systems areplotted below. The velocity profile at the outlet is plotted in Figure 10.Figure 8 -The flow field producted by the simulation using the half systemAppendix 11.1 Page 141-10 10
