“…As a result, it requires Both experimental and numerical studies have been reported in the study of H-rotors. In their wind tunnel experiment Oler, Strickland, Im, and Graham (1983) observed a large vortex on a single-bladed H-rotor. Simão Ferreira, Kuik, Bussel, and Scarano (2009) used the PIV method to visualize vortex shedding from a single-bladed H-rotor.…”
