Particle-laden two-dimensional elastic turbulence
The aggregation properties of heavy inertial particles in the elastic turbulence regime of an Oldroyd-B fluid with periodic Kolmogorov mean flow are investigated by means of extensive numerical simulations in two dimensions. Both the small and large scale features of the resulting inhomogeneous particle distribution are examined, focusing on their connection with the properties of the advecting...
متن کاملEffect of inter - particle collision in particle - laden homogeneous isotropic turbulence
Submitted for the DFD10 Meeting of The American Physical Society Effect of inter-particle collision in particle-laden homogeneous isotropic turbulence OHJOON KWON, CHANGHOON LEE, Yonsei University — It has been known that Inter-particle collision of small spherical particles in particle laden homogeneous isotropic turbulence modifies the statistical characteristics of particle behaviour. For ex...
متن کاملLifting factorization of wavelet multiresolution analysis
Decomposing the wavelet transform in lifting steps allows a simpler implementation of the transform filters and provides the flexibility necessary to satisfy other requirements, e.g., generating non-linear integer-to-integer wavelet transforms. The paper presents a flow-graph approach to the lifting factorization that gives a better insight to the main features of single-phase and two-phase wav...
متن کاملTight wavelet frames for irregular multiresolution analysis
An important tool for the construction of tight wavelet frames is the Unitary Extension Principle first formulated in the Fourierdomain by Ron and Shen. We show that the time-domain analogue of this principle provides a unified approach to the construction of tight frames based on many variations of multiresolution analyses, e.g., regular refinements of bounded L-shaped domains, refinements of ...
متن کاملBuckling of particle-laden interfaces.
In this paper, we investigate the buckling of an oil-water interface populated by micron-sized latex particles using a Langmuir trough. In this work, we extend results of buckling of particle-laden interfaces from the millimeter down to the submicron range while investigating the effect of a different capillary length on the resulting wavelength. The experimental data is compared to the existin...
