The sequence of calculation methods for determining the design and technological parameters of grinding equipment makes it possible to numerically present the results of calculations of rational operating modes of the equipment. The study presents a mathematical description of the dynamics of a two-phase flow inside the grinding chamber of a disintegrator, with the help of which it is possible to determine the speed characteristics of its operating modes for materials with different physical and mechanical properties. The nature of the change in the tangential components of the velocities of the two-phase flow has been established: the range of the current radius of the grinding chamber Ri has been determined, at which the radial components of the velocities of the carrier flow and particles of the ground material continue to increase. As a result of mathematical modeling, it was confirmed that with an increase in the concentration of dust particles in the increasing volume of the grinding chamber, the value of the tangential component of the velocity of a dynamic two-phase flow decreases in relation to the maximum parameters at Ri = 0.15 m by an average of 15.5%. It has been determined that the maximum velocity values for the tangential component are in the limit of Ri = 0.1-0.15 m and are 131 m/s for air, and 127.5 m/s for an average suspended particle with dsr = 40 μm. In the process of developing a mathematical description, it was established that in the range Ri = 0.15 - 0.3 m the increase in the radial components of the velocities of the air carrier medium and the weighted average particle flow is about 14.5%, which, in turn, indicates an increase in the kinetic energy of the crushed particles during the movement of a dynamic two-phase flow from the center to the periphery of the grinding chamber of the disintegrator.","PeriodicalId":9367,"journal":{"name":"Bulletin of Belgorod State Technological University named after.

The purpose of the studies was to assess the possibility of increasing the efficiency of the bead mill when screw blades are installed on the paddle shaft and their influence on the energy state of grinding bodies. Using the EDEM software product, the mathematical planning method of the experiment, a simulation of the process of movement of grinding bodies in the model of the body part of the bead mill was carried out when it was equipped with a pair of two-way screw blades. The obtained regression equation was studied. It describes the dependence of the averaged value of the total kinetic energy of the grinding body on varying factors: the angle of rotation of the beginning of the blade screw starts, the distance between the screw blades, the pitch of the screw blade, and the angular speed of the blade shaft. The possibilities of increasing the average value of the total kinetic energy of the grinding body and regulating the energy state of the grinding bodies have been established.

The necessity of creating a unified stylistic urban environment is substantiated, due to the multiculturalism of architecture and marketing, a multinational population, which leaves its mark on the urban environment and its perception by residents. An analysis of foreign and domestic experience in the use of design code, its impact on architecture, psychological and physical health of a person, economic stimulation and social aspects of public life is carried out, and the problems of modern cities and ways to solve them using design coding are described. Based on the results of the analysis of best practices, the most current trends in the formation of a comfortable urban environment were identified using various design code elements that are most effective and attractive.

The basis for the survey was the check of the technical condition of the balcony slabs of a three-story multi-storey brick residential building in order to determine the degree of wear, possible defects and assess the possibility of further operation of the slab. A structural solution analysis was carried out to assess the technical condition of the building structures. Loads acting on the structures, impacts and operating conditions, the quality of structures, materials and connections were established. This also took into account factors such as the geometric dimensions of structures and their sections; presence of cracks, splits and destruction; condition of protective coatings; broken adhesion of reinforcement to concrete; presence of reinforcement rupture; condition of anchoring of longitudinal and transverse reinforcement; degree of corrosion of concrete and reinforcement. As a result of visual and measuring control, defects and damages having the requirements of operation and leading to a malfunction of the structure were revealed.

A detailed presentation of the exercise is created, encompassing all the essential biomimetic principles based on floristry. When constructing this framework, the primary focus is on integrating sustainable and environmentally conscious architectural concepts, which are paramount to the proposal. During the development of the model, techniques for drawing inspiration from floral morphology and behavioral patterns are examined, along with guidance on how to integrate them into architectural designs. In that respect, the paper strives to identify a set of fundamental elements in a building focused on its usage, sustainability, and maintenance in an environment-friendly mode.

The complex task of ensuring standardized air parameters in high-rise buildings is quite complex due to the presence of the stack effect, the action of which in the cold season leads to an increase in infiltration and energy consumption. In design practice, infiltration calculations are carried out using engineering methods that do not provide identical solutions. To assess the impact of in-filtration on the air regime of unique buildings, numerical calculations or modeling in wind tun-nels are used, which have a certain degree of reliability. The paper reviews the work on the influ-ence of the stack effect on the location of the neutral axis of the building and infiltration. One of the main measures to reduce infiltration is the use of façade structures with low air permeability. The selection of façade structures is more reliably carried out taking into account test results. Ex-perimental data are presented for determining the air permeability of a fragment of a modular fa-cade and their comparison with the regulatory requirements of the Russian Federation and differ-ent countries. The discrepancy between the calculation results using engineering methods and test results is shown. It is proposed to use the volume flow coefficient to determine the volume of infil-tration air when the pressure difference changes over a wide range. Tested structures can be rec-ommended for high-rise buildings to ensure the required tightness.","PeriodicalId":9367,"journal":{"name":"Bulletin of Belgorod State Technological University named after.

One of the key methods for estimating this dimension is cell counting. The fractal dimension of pores indicates the degree of their dense distribution and is closely related to the physical properties of the material, such as heat and sound insulation. The results of the study showed that an increase in the fractal dimension of pores is associated with an increase in the number of smallest pores and the complication of their spatial arrangement. At the same time, the use of the cell counting method allows to estimate accurately this fractal dimension, based on the number of cells containing pores at different scales. One of the significant aspects is the correlation of the fractal dimension of pores with their area and size. This makes it possible to evaluate the roughness of pores and their distribution in the material, as well as to understand how an increase in pore size leads to a decrease in their number and thickening of the walls between them. The fractal dimension of pores makes it possible to characterize the structure of the pore space, which is important for understanding the microstructure of the material. Manipulating the microstructure of cellular concrete using fractal dimension analysis can improve its thermal insulation, strength and sound insulation, opening new possibilities for creating more efficient building materials","PeriodicalId":9367,"journal":{"name":"Bulletin of Belgorod State Technological University named after.
