Referring to the previous paper Rizzo et al.

The purpose of CFD analyses is to describe vortex shading and to compare data in order to identify characteristics for each different geometrical shape considered; three dimensional models are used to evaluate the pressure streamlines and vectors. Analysis with POD technique aims instead to describe the action on hyperbolic paraboloid surfaces of randomly fluctuating wind pressure fields and wind tunnel tests data are used to evaluate pressure modes.

Abstract

Referring to the previous paper Rizzo et al. [1] the aim of this research has been to investigate the aerodynamic behaviour of structures tested in a wind tunnel with Proper Orthogonal Decomposition (POD) technique and with Computational Fluid Dynamic (CFD) analyses. The purpose of CFD analyses is to describe vortex shading and to compare data in order to identify characteristics for each different geometrical shape considered; three dimensional models are used to evaluate the pressure streamlines and vectors. Analysis with POD technique aims instead to describe the action on hyperbolic paraboloid surfaces of randomly fluctuating wind pressure fields and wind tunnel tests data are used to evaluate pressure modes. Moreover POD technique is used to obtain min and max values of pressure coefficients only with few data. © Museo Ideale L. Da Vinci.
