Benefits of Spectral Proper Orthogonal Decomposition in Separation of Flow Dynamics in the Wake of a Cantilevered Square Cylinder
Abstract
A comparative analysis is presented to illustrate the benefits of time-domain spectral proper orthogonal decomposition (SPOD) over traditional proper orthogonal decomposition (POD) in separating coherent contributions within narrow spectral bandwidth. The wake of a cantilevered square cylinder of height-to-width ratio h/d=4 protruding a thin laminar boundary layer (δ/d=0.21) is investigated at a Reynolds number (Re) of 10600 using time-resolved …
