Study on Flow Characteristic of Sub-/Super-Sonic Mixing Layer

open access: yesXibei Gongye Daxue Xuebao, 2020
In order to obtain the flow characteristics of sub-super-sonic mixing layer including velocity distribution, pressure distribution and development of mixing layer, experimental and numerical investigations were conducted.

Self-Similar Turbulent Dynamo [PDF]

open access: yesPhysical Review Letters, 2004
The amplification of magnetic fields in a highly conducting fluid is studied numerically. During growth, the magnetic field is spatially intermittent: it does not uniformly fill the volume, but is concentrated in long thin folded structures. Contrary to a commonly held view, intermittency of the folded field does not increase indefinitely throughout ...

The Expansion of Self-similar Functions in the Faber–Schauder System

open access: yesМоделирование и анализ информационных систем, 2017
Let \(\Omega = A^{N}\) be a space of right-sided innite sequences drawn from a nite alphabet \(A = \{0,1\}\), \(N = \{1,2,\dots\}\). Let $$\label{rho} \rho(\boldsymbol{x},\boldsymbol{y}) =\sum_{k=1}^{\infty}|x_{k} - y_{k}|2^{-k}$$- be a metric on ...

Elementary Fractal Geometry. 2. Carpets Involving Irrational Rotations

open access: yesFractal and Fractional, 2022
Self-similar sets with the open set condition, the linear objects of fractal geometry, have been considered mainly for crystallographic data. Here we introduce new symmetry classes in the plane, based on rotation by irrational angles.

Spherically Symmetric, Self-Similar Spacetimes [PDF]

open access: yes, 2001
Self-similar spacetimes are of importance to cosmology and to gravitational collapse problems. We show that self-similarity or the existence of a homothetic Killing vector field for spherically symmetric spacetimes implies the separability of the ...

Intransitive self-similar groups [PDF]

open access: yesJournal of Algebra, 2021
A group is said to be self-similar provided it admits a faithful state-closed representation on some regular $m$-tree and the group is said to be transitive self-similar provided additionally it induces transitive action on the first level of the tree. A standard approach for constructing a transitive self-similar representation of a group has been by ...

Notes on the Transversality Method for Iterated Function Systems—A Survey

open access: yesMathematical and Computational Applications, 2023
This is a brief survey of selected results obtained using the “transversality method” developed for studying parametrized families of fractal sets and measures. We mostly focus on the early development of the theory, restricting ourselves to self-similar

Kinematic self-similarity [PDF]

open access: yesClassical and Quantum Gravity, 1997
Self-similarity in general relativity is briefly reviewed and the differences between self-similarity of the first kind and generalized self-similarity are discussed. The covariant notion of a kinematic self-similarity in the context of relativistic fluid mechanics is defined.

Self-similar hyperbolicity [PDF]

open access: yesErgodic Theory and Dynamical Systems, 2017
In this paper we consider expansive homeomorphisms of compact spaces with a hyperbolic metric presenting a self-similar behavior on stable and unstable sets. Several applications are given related to Hausdorff dimension, entropy, intrinsically ergodic measures and the transitivity of expansive homeomorphisms with canonical coordinates.
