Abstract:
The object of research is the process of granulation of nitrogen mineral fertilizers by the method of sprinkling. One of the most problematic areas is the lack of certainty regarding the dynamics of the temperature change of the granule when it is cooled by air in the granulation tower. The paper considers the process of urea granulation using a rotating vibrating granulator. The scheme of the rotating vibrating granulator as part of the experimental stand for granulating liquid urea is presented, the method of conducting experimental studies and the design parameters of the granulator are des

Object of research: The study investigates the process of cooling mineral fertilizer granules in a granulation tower, focusing on the relationship between granule size and their final temperature after cooling. Investigated problem: The key problem addressed is the insufficient cooling of granules due to increased ambient air temperatures, changes in process parameters, and limitations of existing ventilation systems in granulation towers, which affect granule quality. Main scientific results: The research presents a mathematical model that describes the heat transfer processes occurring durin

Abstract:
The object of research is the heat transfer coefficient between pellets and air flow in industrial granulation towers. The problem lies in the difficulty of optimizing the heat transfer process. As a result of experiments and analysis, it was shown that each granulating tower for the production of mineral fertilizers has unique properties that significantly affect the efficiency of heat transfer. There are general mathematical models, but for accurate modeling and optimization of heat transfer, the unique characteristics of each production must be taken into account. The results showed that cr

In the process of preparing asphalt-based spherical activated carbon, the molten asphalt must be formed into qualified spherical particles through the granulation process. Taking the process of molten asphalt granulation as the research direction, this paper carries out an asphalt rotational viscosity experiment and a thermogravimetric differential thermal experiment (TG–DSC), and obtains the optimal temperature and viscosity values for the asphalt granulation process. The fluent module in ANSYS software is used to input the known asphalt and prilling tower parameters. Based on the asphalt pri

The main problem that was solved was the analysis of the temperature mode of cooling the granules to increase their strength and quality, as well as to reduce the probability of their destruction during storage and transportation. The design of a rotating vibrating granulator (RVG) and a mathematical model for calculating the temperature of granules and air at different stages of the granulation process are presented.

Aiming to understand the asphalt granulation and separation processes in a new technique of solvent deasphalting, this work performs a detailed numerical study of the gas flow behaviors in a spray granulation tower with array nozzles. The influence of nozzle distances and jet angles on the fluid dynamics of the tower, especially on the double swirling flow, is investigated. The simulation results reveal many interesting phenomena, which include a flow consisting of two distinct regimes, a multistage flow development of jet array and a strong dependence of the velocity distribution on the nozzl

Movies of the solar granulation were made simultaneously at 5575 Å and 1.64 μm using the Vacuum Tower Telescope at NSO/SP. A 128 × 128 HgCdTe array was used in the infrared and an RCA 504 CCD in the visible. From the movies, we determine and compare statistical properties of the granulation and seeing conditions.

Abstract:
The Sun presents unusual problems for wave-front sensing. Unlike nighttime objects, the Sun does not provide natural, high-contrast point sources, and the creation of artificial beacons bright enough to be visible against the solar disk remains problematic with current technology. Conventional wave-front sensors, such as shearing interferometers and Shack-Hartmann systems, do not appear to operate effectively with targets such as solar granulation. Motivated by the experience with the Lockheed AO system built about a decade ago, we have performed a series of experiments at the Sacramento Peak
