The article presents results of numerical simulation and experimental studies of elastic wedge wave propagation in cylindrical wedges with positive and negative curvature in the 100–600 kHz frequency range. It is shown that wedge waves in such structures have dispersion and their localization at the edge of the wedge is stronger than that of straight wedges. The results of a study for cases where the inner surface of the wedge is bounded by fluids with different viscosities (water, SAE 10W-30 motor oil, 86% glycerol aqueous solution) are presented.
