З 1961 р. у ХПІ видається збірник наукових праць "Вісник Харківського політехнічного інституту".
Згідно до наказу ректора № 158-1 від 07.05.2001 року "Про упорядкування видання вісника НТУ "ХПІ", збірник був перейменований у Вісник Національного Технічного Університету "ХПІ".
Вісник Національного технічного університету "Харківський політехнічний інститут" включено до переліку спеціалізованих видань ВАК України і виходить по серіях, що відображають наукові напрямки діяльності вчених університету та потенційних здобувачів вчених ступенів та звань.
Зараз налічується 30 діючих тематичних редколегій. Вісник друкує статті як співробітників НТУ "ХПІ", так і статті авторів інших наукових закладів України та зарубіжжя, які представлені у даному розділі.

    Management of archive and library institutions: expert evaluation of the quality of activities
    (Національний технічний університет "Харківський політехнічний інститут", 2024) Bachynska, Nadiia; Tverytnykova, Elena; Drozdova, Tetiana; Salata, Halyna
    The use of information technologies in the practical activities of archival and library institutions is becoming more and more widespread. This actualizes the study of the issue of library and archive management and the implementation of quality management systems in the activities of libraries and archives. This problem is exacerbated by the current emergency situation in which archival and library institutions operate. Therefore, it is necessary to involve modern approaches to assessing the quality of library and archive management. The use of expert methods for evaluating multi-faceted systems has a long tradition. Expert assessment methods are used in various fields, in particular, during crisis situations of managerial and socio-economic problems, analysis and forecasting having a large number of social factors. The involvement of a number of methods of related disciplines, including interviewing, questionnaires, surveys, the Delphi method, brainstorming, conference of ideas, etc., contribute to the effective analysis of the management system of a scientific or educational institution. The implementation of the method of expert evaluations in the work of scientific institutions, in particular the archival and library direction, is especially relevant, since the problems of ensuring the quality of their activities are solved with the help of these methods. The quality of activity of the scientific and technical library and archive based on the involvement of experts from three groups was monitored. These are representatives of the teaching staff, researchers and students. The evaluation of such indicators as the process of quality information support of education and research was carried out; the process of reengineering and maximum automation; the process of providing library and archival services. As a result, the positive and weak points of the library and archive institution management were revealed. Based on the results of the analysis, the top management of archival and library institutions should set the new goals regarding the quality level of library and archival services provided, establish a strategy for increasing user satisfaction, assessing the suitability of the structure and resources for future development.

    Identification of the coefficient in the diffusion model of hydrodynamic flow in a chemical reactor
    (Національний технічний університет "Харківський політехнічний інститут", 2024) Gamzaev, Kh. M.; Bayramova, N.Kh.
    A chemical technological process taking place in a chemical reactor with a second-order chemical reaction is considered. A one-parameter diffusion model for nonstationary flows is proposed for the mathematical description of the hydrodynamic flow in the reactor. Within the framework of the proposed model, the task is set to identify the longitudinal mixing coefficient according to an additionally specified condition regarding the concentration of the reagent under study at the outlet of the reactor. A special representation is proposed for the diffusion terms in the hydrodynamic flow model in the reactor. The method of difference approximation is used to construct a discrete analogue of this model using explicit-implicit time approximation for diffusion terms. Decomposition is used to numerically solve the resulting system of linear difference equations, as a result of which the system of difference equations for each discrete value of a time variable splits into two mutually independent linear subsystems, each of which can be solved independently, independently of each other. As a result, an explicit formula was obtained for determining the approximate value of the longitudinal mixing coefficient in a hydrodynamic flow. Based on the proposed computational algorithm, numerical calculations were performed for model problems.
