A Volumetric Approach to Wake Reduction: Design, Optimization, and Experimental Verification

Figure 10

The pressure fields between the uncloaked sphere (a) and the cloaked sphere (b) illustrate a localization of the pressure drop in the axisymmetric cross section from the control case to the PVC case. Note the location of the PVC boundaries in (b) and how the pressure immediately downstream region has a notably reduced magnitude of negative pressure.
