The global mode visualization technique presented in Venning et al. [1] is extended to use two cameras, simultaneously recording a 3D cavitating flow from opposite directions. The cavitating flow investigated is that about a sphere at a transcritical Reynolds number of 1.5 × 106 and a cavitation number of 0.8. High-resolution data, in both time and space, allows detailed mode shapes to be obtained. The addition of the second camera significantly reduces the potential for ambiguity about the nature of the shedding modes and adds additional information in regions that would otherwise be obscured in a single-camera experiment. The global distribution of power and the phase for each cavity shedding mode are described, confirming a symmetric and asymmetric mode.
