Hyperbolicity, shadowing directions and sensitivity analysis of a turbulent three-dimensional flow

Semi-Hyperbolicity and Bi-Shadowing

Preface In the beginning of 90s the authors of this monograph proposed a generalization of the concept of hyperbolicity, first for differentiable mappings and later for Lipschitz mappings, which they called 'semi-hyperbolicity'. This arose indirectly in the context of their research at that time on the effect of spatial discretization on the behavior of a dynamical system, in particular that of...

Continuous Inverse Shadowing and Hyperbolicity

We study the concepts of continuous shadowing and continuous inverse shadowing with respect to various classes of admissible pseudo orbits, and characterize hyperbolicity and structural stability using the notion of continuous inverse shadowing.

Investigations of Three- Dimensional Turbulent Cavity Flow Using Large Eddy Simulation Approach

THREE DIMENSIONAL MODELING OF TURBULENT FLOW WITH FREE SURFACE IN MOLD FILLING

In the present study a Finite Difference Method has been developed to model the transient incompressible turbulent free surface fluid flow. A single fluid has been selected for modeling of mold filling and The SOLA VOF 3D technique was modified to increase the accuracy of simulation of filling phenomena for shape castings. For modeling the turbulence phenomena k-e standard model was used. In or...

‏‎a phonological contrastive analysis of kurdish and english‎‏

deposite the different criticisms on contrastive analysis it has been proved that the results of it(when processed)can be usuful in a tefl environment,specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims. the consonants,vowels,stress and intonation of the twolanguages are described by the same model-ta...
