Figure 7:

Comparison of the steady-state pressure (top panels) and velocity (bottom panels) distributions between the present IIM (left panels) and the standard IB method (right panels) for the inclined channel with grid spacing h = 0.078. The results are qualitatively similar to those of the horizontal case shown in Fig. 6, but note that here we are using a finer computational grid, and so both the IIM and IB results are more accurate than those of Fig. 6.
