In order to propose a simpler and more effective method to quantitatively analyze the
macroscopic basic deformation properties such as tension, bending and shear of the skew …

To fully use the land resource in the urban regions of metropolises, high-rise buildings of
large aspect ratio maybe preferred for the new constructions. To systematically investigate …

Fluid dynamics systems driven by dominant, near-periodic dynamics are common across
wakes, jets, rotating machinery and high-speed flows. Traditional modal decomposition …

We present a formulation of proper orthogonal decomposition (POD) producing a velocity–
temperature basis optimized with respect to an H 1 dissipation norm. This decomposition is …

Vortex wandering is one of the most basic unsteady flow characteristics of the tip leakage
vortex (TLV) in compressors. In this study, stereo particle image velocimetry (stereo-PIV) has …

We experimentally investigate the 3-D flow characteristics caused by synthetic jet in the
turbulent boundary layer (TBL), with the aim of analyzing the differences and similarities of …

The cornerstone assumption of equilibrium of the small and intermediate scales in the
classical view of turbulence (K41–the combined efforts of Kolmogorov, Batchelor and …

The Karman-Howarth-Monin-Hill (KHMH) equation has been widely applied to scale-by-
scale turbulent energy cascade studies in recent years, however, the forms and …

This thesis concerns various aspects of the proper orthogonal decomposition (POD) applied
to turbulent flows and of the length scales characterising flow structures educed using the …
