Internal gravity waves in the energy and flux budget turbulence-closure theory for shear-free stably stratified flows

We have advanced the energy and flux budget turbulence closure theory that takes into account a two-way coupling between internal gravity waves (IGWs) and the shear-free stably stratified turbulence. This theory is based on the budget equation for the total (kinetic plus potential) energy of IGWs, the budget equations for the kinetic and potential energies of fluid turbulence, and turbulent fluxes of potential temperature for waves and fluid flow. The waves emitted at a certain level propagate upward, and the losses of wave energy cause the production of turbulence energy. We demonstrate that due to the nonlinear effects more intensive waves produce more strong turbulence, and this, in turn, results in strong damping of IGWs. As a result, the penetration length of more intensive waves is shorter than that of less intensive IGWs. The anisotropy of the turbulence produced by less intensive IGWs is stronger than that caused by more intensive waves. The low-amplitude IGWs produce turbulence consisting up to 90% of turbulent potential energy. This resembles the properties of the observed high-altitude tropospheric strongly anisotropic (nearly two-dimensional) turbulence.Peer reviewe

Dilatometric characteristics of weakly sintered ceramics

Thermal expansion of refractory ceramics CaZrO3, MgAl2O4, La2Zr2O7 and YSZ-12 was studied. The samples of the complex oxides were synthesized by solution combustion synthesis with glycine; the fuel:oxidant ratio was varied depending on the character of redox reaction. The linear thermal expansion coefficient (LTEC) of ceramics was measured on the samples with an initial density 23–52%. The maximal sinterability of 89–92% after 6 h annealing at 1550 °С was demonstrated by La2Zr2O7 and YSZ-12, and the minimal values (78–82%) – by CaZrO3 and MgAl2O4. All materials have close LTEC values, from 9.0 to 9.6·10–6 K–1

Astana the capital of Kazakhstan and Astanas in Siberia as a linguistic-cultural aspect of the national Islam of Eurasia

By the time Islam penetrated into the Siberia and Kazakhstan, these territories were inhabited by various Turkic nomadic tribes whose spiritual and religious life was very varied. From the earliest age, a variety of cultural and ideological systems coexisted, including huge range of autochthonous ancient beliefs based on nature worship and ancestor worship, involving magic and the deification of the sky (Tengrism). After unification with Islam, these beliefs could later be found in the culturally-based traditional lifestyles of Siberian Tatars and Kazakhs. This is particularly true in the peripheries of the spread of Islam - in Siberia and Northern Kazakhstan, with their largely nomadic ways of life. The authors speculate on the name, astana, given to a succession of topographical objects, suggesting it represents a method for concealing the sacred in the profane. In modern socio-cultural reality, considering the mythological potential of a name involves examining fundamental characteristics of the culture such as 1. the interactive nature of culture itself, 2. its mythology, 3. its appeal to the potential of the past in search of the lost eternal values, and 4. the primacy of cultural interactions with respect to social processes. Whether the reader agrees or disagrees with this, one thing is clear: everything, even the tiniest shades of meaning that may arise in the human mind, must be considered. The vivid, powerful, multifaceted image that arises from the valuation of toponymical objects is valuable for the modern man; it rebuilds the ruined individualism and immensity of the world, thus broadening our own cultural space. The sacral complex of an astana can be understood as a kind of socio-cultural communication which provides a record of a collective tradition

Modern software features for shape optimization of shells

Shape optimization, as one of the types of structural optimization problems, is an important process in the design of shells, since it contributes to the creation of a structure with fine performance characteristics, expansion of design variations and knowledge base to obtain high-quality results. To solve the problems associated with determining the shape and creating more advanced structures, software packages include a special optimization module, which can be based on one or more mathematical methods, the purpose of which is to provide the best solution in the shortest possible time. The research is focused on the process of shape optimization in three well-known universal software packages: Ansys Mechanical, COMSOL Multiphysics and Simulia Abaqus, as well as in Rhinoceros modeling software with a special visual Grasshopper plugin. The purpose of the study is to analyze the technology of shape optimization in four software packages and to compare them with each other in terms of the problem-solving process, user interface, the fullness of libraries, accessibility for educational purposes and system requirements for a computer. The authors specify and describe the characteristic features of each software package. It was found that all the software packages under consideration are equipped with great opportunities for shape optimization of structures and have a variety of functionality for solving this type of tasks. The development of optimization technology in calculation and modeling software packages will allow obtaining the most effective solutions in the process of designing shells of complex shapes
