Convective Drying in the Multistage Shelf Dryers: Theoretical Bases and Practical Implementation

The main advantages regarding the convective drying of the granular materials in the multistage dryers with sloping perforated shelves were represented. Peculiarities of the shelf dryers’ hydrodynamics were shown in the research. Various hydrodynamic weighing modes were experimentally justified, and the relevant criteria equations were obtained. The results of investigations regarding the interphase heat and mass transfer were given; criteria dependencies, which predict heat and mass transfer coefficients in the shelf dryers, were proposed. A method to assess the efficiency of the dehydration process at the separate stages of the device and in the dryer, in general, was proposed. The algorithm to define the residence time of the granular material on the perforated shelf with a description of the author’s software product for optimization calculation was shown. The shelf dryers’ engineering calculation method was presented in this work. The original constructions of devices with various ways to control the residence time of the granular material that stays in their workspace were described. The testing results of the shelf dryer to dry granular materials, such as coarse- and fine-crystalline potassium chloride, sodium pyrosulfate, and iron and nickel powders, were demonstrated

Educational Marketing Tools on the Way to Costumer: Analogies with Approaches in Technical Systems Description

The article deals with the creation of a "box" model for describing the non-material complex “marketing of educational services” - “university” by analogy with the description of technical systems. The “box” approach has been studied in various industries, including marketing. Studies have shown that despite the similarity of names, the “box” approach in describing marketing strategies cannot fully explain the mechanism of influence of the educational service provider (university) on the customer. The results of the bibliometric analysis for the queries “educational market”, “neuromarketing”, and “educational marketing” showed that the process of marketing educational products takes place in the directions from the “supplier” of services to the “supplier” of services. This feature was considered when describing the educational marketing complex using the “box” approach. An attempt is made to describe each characteristic of the “white” box model concerning the complex “marketing of educational services” - “university”. In the course of the description, it was established that the “box” model should be supplemented with blocks for the complex testing and parametric identification of the model’s output parameters (responses). The list of parameters X, K, U, Z, and Y can be expanded; however, the fundamental approach to modeling a system will remain unchanged, in the center of which is the customer and the supplied. A feature of the model is a non-standard approach to parametric identification. In contrast to the material model, the intangible object “marketing of educational services” - “university” can have several options for parametric identification. The “white” box model with blocks for the complex testing and parametric identification of output parameters (responses) of the model allows you to move from a qualitative to a quantitative description of the main characteristics of an object and predict its behavior depending on the purpose of parametric identification

Directed Fluidized Bed in Drying Machines: Main Stages of Optimization Calculation

The article deals with the study of main hydrodynamic characteristics of the directed fluidized bed in gravitation shelf dryers. The algorithm to calculate hydrodynamic characteristics of the directed fluidized bed in the dryer’s workspace is described. Every block of algorithm has theoretical model of calculation. Principles of disperse phase motion in various areas in the gravitation shelf dryer are established. The software realization of author’s mathematic model to calculate disperse phase motion trajectory in free and constrained regime, disperse phase residence time in the dryers’s workspace, polydisperse systems classification is proposed in the study. Calculations of disperse phase motion hydrodynamic characteristics using the software product ANSYS CFX, based on the author’s mathematic model, are presented in the article. The software product enables to automatize calculation simultaneously by several optimization criteria and to visualize calculation results in the form of 3D images. The data on the construction of a computational model and computational grid for modeling the gas flow motion is presented. The results of determining the gas flow velocities field in the workspace of a gravitational shelf dryer distinguishing the specific zones of the drying agent’s motion are demonstrated. High and low-intensity places of gas flow are established in the dryer.The residence time of particles in the dryer is calculated depending on the technological and design parameters of the drying process, in particular, the constraint degree of the particle flow. The influence degree of the dryer’s features and its operating mode on the expected “hydrodynamic” residence time of the material in the device is established. The obtained value of the “hydrodynamic” residence time of the material in the device is compared with the drying time to find the optimal design of the dryer

Knowledge marketing: M4I-mix model of evaluation

The article is devoted to studying knowledge marketing as a tool for promoting educational and scientific services from the developer (university) to the consumer (industry and business). The main stages of knowledge generation following the DIKW model and the procedure for their further implementation are shown. Based on the bibliometric analysis of keywords clusters and the most popular research topics in the field of "knowledge marketing", the relevance of implementing the chain "idea - investigation - implementation - industry" was confirmed. The M4I-mix approach is proposed for detailing the main processes occurring at each stage of knowledge marketing and identifying significant indicators that should be influenced. Examples of using the M4I-mix approach to promote educational services and commercialize research results are given

Understanding the essence of immersive marketing for educational services and knowledge transfer

The article deals with the creation of educational immersive marketing models. The concept of immersive marketing involves multi-vector interaction of internal and external stakeholders at the stage of creating a “wrapper” of an educational program. Immersive marketing is implemented from inside the university with the help of influencers (students who are involved in the joint preparation of educational scenarios in a virtual or real interactive environment), as well as from the outside due to the participation of external stakeholders in the formation of the image of the educational program. The paper analyzes various marketing mix models, marketing “tips” for Gen Z, Gen Z, and Gen Alpha, as well as the possibilities of creating an interactive educational environment in the era of total digitalization. Elements that provide immersive knowledge transfer in attracting potential customers of educational services are selected from marketing mix models, marketing “tips” and characteristics of the educational environment. The “Mix – Tips – Transformation” (MTT) approach was proposed, which was transformed into the concept of immersive marketing “Emotions – Feelings – Senses – Environment” (EFSE). The concept of immersive marketing EFSE allows you to cover all vectors of interaction between the stakeholders of the educational program and offer a multi-level model of immersive marketing. The effectiveness of the EFSE model and its elements (including the multidimensional immersive marketing model) can later be confirmed or refuted by the results of surveys and performance testing along the “unit testing – quality control – quality assurance” chain

Educational Resilience Through the Armed Conflicts: A Bibliometric Analysis

This article conducts a bibliometric analysis to examine the scholarly discourse on educational resilience in the context of armed conflicts. It has explored how educational systems adapt, persist, and recover in adversity. The Biblioshiny App, the R programme Bibliometrix, the VOSviewer 1.6.16, and the Scopus tools were utilised. The analysis spans publications from 2000 to 2024, focusing on keywords such as “educational resilience”, “education recovery”, “armed conflicts”, “war”, “violence”, and “military conflicts”. The scope of the analysis was restricted to conference proceedings, books, and articles; other kinds of publications were not included. Given the wide range of geographic origins implied by the emphasis on emerging and frontier markets, no language limits were placed. There were no limitations on the research’s scope because the subject is transdisciplinary. 2,797 papers were chosen for analysis from the Scopus database based on these criteria. The study highlights the evolution of research themes, noting significant growth in publication activity post-2014 and topic changing post-2017, with notable contributions from researchers in conflict-affected regions. An analysis of the dynamics of public interest in the topic of educational recovery, conducted with the help of Google Trends, showed that the peak of interest fell in January 2022 (educational rehabilitation after the pandemic). More than 70% of the papers fall into the top three subject areas ‒ Social Sciences, Medicine, and Arts and Humanities ‒ which confirms the interdisciplinary nature of research on educational resilience in crisis situations. Most scientists on this topic are affiliated with the United States, the United Kingdom, India, China, and Australia. The United States and the United Kingdom have the longest histories of collaborative publications. The co-authorship analysis revealed that the most powerful regional cooperation network is formed by Australia, China, Hong Kong, India, Japan, New Zealand, the Philippines, Singapore, South Korea, Taiwan, Thailand, and Vietnam. The clustering of studies by keywords showed that the most powerful is a cluster of studies devoted to the impact of conflict on educational systems, resilience and recovery strategies, and political implications for education in emergencies
