Shearing Expansionfree Spherical Anisotropic Fluid Evolution

چکیده
Spherically symmetric expansionfree distributions are systematically studied. The whole set of field equations and junction conditions are presented for a general distribution of dissipative anisotropic fluid (principal stresses unequal), and the expansionfree condition is integrated. In order to understand the physical meaning of expansionfree motion, two different definitions for the radial velocity of a fluid element are discussed. It is shown that e-mail: [email protected] e-mail: [email protected] e-mail: anzhong [email protected]

Three-Dimensional Geostatistical Analysis of Rock Fracture Roughness and Its Degradation with Shearing
Three-dimensional surface geometry of rock discontinuities and its evolution with shearing are of great importance in understanding the deformability and hydro-mechanical behavior of rock masses. In the present research, surfaces of three natural rock fractures were digitized and studied before and after the direct shear test. The variography analysis of the surfaces indicated a strong non-line...
متن کاملTotally Anisotropic Cosmological Models with Bulk Viscosity for Variable G and Λ
Einstein’s field equations with variable gravitational and cosmological constants are considered in the presence of bulk viscous fluid for the totally anisotropic Bianchi type II space-time in such a way as to preserve the energy momentum tensor. We have presented solutions of field equations which represent expanding, shearing and non-rotating cosmological models of the universe. The physical ...
متن کاملRole of Pressure in Quasi-Spherical Gravitational Collapse
We study quasi-spherical Szekeres space-time (which possess no killing vectors) for perfect fluid, matter with tangential stress only and matter with anisotropic pressure respectively. In the first two cases cosmological solutions have been obtained and their asymptotic behaviour have been examined while for anisotropic pressure, gravitational collapse has been studied and the role of the press...

Microkinetics models for the partial oxidations of ethylene and of methanol on silver catalysts are coupled with computational fluid dynamics and implemented in a randomly packed bed of 120 spherical particles. The model includes interactions of the elementary reaction steps and transport inside the particles and the flow field. The effects of using the full implementation of the microkinetics ...
متن کاملAnisotropic Bianchi Type-III Bulk Viscous Fluid Universe in Lyra Geometry
An anisotropic Bianchi type-III cosmological model is investigated in the presence of a bulk viscous fluid within the framework of Lyra geometry with time-dependent displacement vector. It is shown that the field equations are solvable for any arbitrary function of a scale factor. To get the deterministic model of the universe, we have assumed that (i) a simple power-law form of a scale factor ...
