'MULTIRESOLUTIONAL-PROPER ORTHOGONAL' HYBRID ANALYSIS ON TURBULENT STRUCTURES IN OPEN-CHANNEL COMPLEX GEOMETRY FLOWS

Publikováno v: International Journal of Wavelets, Multiresolution and Information Processing. :297-310

We propose a hybrid expansion that consists of a multiresolution approximation (MRA) and a proper orthogonal decomposition (POD) to analyze turbulent flow structures in open-channel flows with complex geometries. The open-channel cavity flows are exa

ANALYSIS OF ORGANIZED TURBULENCE IN OPEN-CHANNEL FLOW OVER CONCAVE BED USING TWO-DIMENSIONAL WAVELET TRANSFORM

Autor: Hitoshi Miyamoto, Tohru Kanda, Daisuke Yamanaka

Publikováno v: PROCEEDINGS OF HYDRAULIC ENGINEERING. 46:511-516

In the present paper, we examine organized motions along a turbulent mixing layer in an open-channel flow analyzed by using wavelet transforms. Experimental data of velocity vectors are collected from a particle image velocimetry (PIV). At first, a m

Publikováno v: PROCEEDINGS OF HYDRAULIC ENGINEERING. 46:1091-1096

An in-situ experiment on hypolimnic aeration has been carried out in a eutrophic reservoir. Micro air bubbles were discharged into the anaerobic hypolimnion to supply oxygen and improve water quality. The system has been in operation since March in 1
