Proper orthogonal decomposition study of approach wind-building pressure correlation

Reduced-Order Models of Unsteady Viscous Flows in Turbomachinery Using Viscous–inviscid Coupling

“…The POD is a technique that allows one to obtain good approximations of the spatial modes of vibration and the dynamics of a system using the response of the system to various excitations. Introduced in the context of meteorology and wind engineering to analyze experimental data (Cenedese et al 1997;Jeong & Bienkiewicz 1997;Kikuchi et al 1997;Sahan et al 1997;Tamura et al 1997), the POD has been used for a wide variety of problems, such as wind loads calculations (Ho et al 1995;Bienkiewicz 1996;Uematsu et al 1997). The wide applicability of the method is due to the fact that it is only based on the assumption of a low-dimensionality of the dynamics of large systems (Chambers et al 1988;Georgiou & Schwartz 1996).…”

Identification of meaningful coherent structures in the wind-induced pressure on a prismatic body

“…Tamura et al, 1997;Holmes, 1990;Kareem and Cheng, 1999). Sometimes the results of the analyses appeared encouraging, but there is a general opinion that PCA modes is unable to identify physicallymeaningful CSs (e.g.…”

Contributions to member stresses due to overall wind-induced behaviors of thin-walled cylindrical shell

“…The proper orthogonal decomposition (POD) method has been proved to be an efficient approach to deriving the principal coordinate system for observing individual phenomena, as mentioned in Tamura et al (1997Tamura et al ( , 1999. The main objective of the POD analysis in this paper was to expand wind pressure data from limited measurement points to the whole surface of the model by using an obtained principal coordinate system.…”
