Proper Orthogonal Decomposition Analysis and Modelling of the wake deviation behind a squareback Ahmed body

Berengère Podvin, Stéphanie Pellerin, Yann Fraigneau +2

We investigate numerically the 3-D flow around a squareback Ahmed body at Reynolds number Re = 104. Proper Orthogonal Decomposition (POD) is applied to a symmetry-augmented databas…
