Schematic of various rib profiles examined. Profiles include trapezoidal shapes (profile configurations 1, 2, 3, 4), pyramid-valley shapes (profile configurations 5, 6, 7, 8) and saw-tooth shape (profile configurations 9, 10, 11, 12).

Comparison of present measurements with published data: (a) stationary, comparisons with Han et al. 1; (b) rotating, smooth inlet channel, Re=5000, Ro=0.2. Triangular symbols are data from Han et al. 20.
Grahic Jump Location
Fully developed cell averages of the leading and trailing surfaces of the inlet duct at Re=30,000 and Ro=0.3. Darkest shade represents profiled ribs, intermediate shade represents rectangular ribs with P/e=7.0, and lightest shade represents rectangular ribs with P/e=10.5.

Spanwise-averages in the high-resolution cells for rectangular ribs and profiled ribs: Configuration 7 (top wall–valley, bottom wall–pyramid) Re=30,000, Ro=0.3, and P/e=7.0
Grahic Jump Location
Spanwise-averages in the high-resolution cells for rectangular ribs and profiled ribs: Configuration 9 (saw-tooth shaped with 2-pyramids-1-valley), Re=30,000, Ro=0.3, and P/e=7.0
