Time–frequency analysis of time-series obtained with hot-wire anemometry is performed through a procedure based on proper orthogonal decomposition and spectral components are extracted with a technique that provides an increased efficiency for fluid dynamic applications.time-frequency analysisbluff body aerodynamicstriangular prismproper orthogonal decompositiontext::journal::journal article::research article
