Fig. 2 Impact of mesh density on LES results. Time-averaged velocity results for iLES-SOU (11 M and 37 M), iLES (11 M and 37 M), and iLES-BCD (11 M) models (top). The impact of grid resolution on the SVC jet with iLES-SOU models is highlighted by the white dashed triangles. The absolute velocity d... More

Fig. 5 IVC and SVC mixing comparison. ( a ) Relative differences (compared to LES-WALE) in the passive scalar (1 for SVC, 0 for IVC) assigned to inlet flows compared to the 11 M cell URANS (top), iLES-SOU (middle), and iLES-BCD (bottom) are shown on a cross-sectional plane through the RA. The red ... More

Published Online: June 7, 2022
Fig. 6 iLES-SOU and LES with WALE energy spectra. The energy spectra are plotted for the 11 M cell iLES-SOU (left) and LES-WALE (right), when IVC and SVC flow rates are equal, at several points of interest (1–6) in the RA. The cross-sectional planes show instantaneous velocities at 3.5 s. The gray... More
