摘要: Fast-response pressure-sensitive paint (PSP) was used in this work for a study of the unsteady surface pressures resulting from complex separated flow over hemispherical turret model. The includes several distinct features such as flat window and crevices that are based on functional requirements, but also introduce interesting additional compact features. Three high-speed cameras imaged luminescence at 2 kHz, producing pressure time histories entire These data were integrated model order to determine loads. PSP successfully resolved very small had aperiodic fluctuations least kilohertz.
