Use permitted under Creative Commons License Attribution 4.0 International (CC BY 4.0).An elective course “Nuclear Physics” was developed for high school students, including a traditional textbook, a computer application and various interactive educational materials and 3D models available on mobile devices using QR codes. The main idea of the course can be formulated as “From Nuclear Physics to Nuclear Technologies”. The elective course includes not only basic laws of nuclear physics, but also the application of these laws in nuclear astrophysics, in the synthesis of new elements, nuclear energy, nuclear medicine, ecology and radiobiology. Each chapter in the textbook provides links to additional digital materials: video lectures, examples of problem solving and additional materials for advanced study. At the end of the textbook, you can also find the references to a virtual practicum on nuclear physics, final tests, and approximate research and project works. The textbook pays special attention to the modern achievements of nuclear physics. It contains information of modern international experiments, conducted at JINR and other international scientific centers.
- ПубликацияОткрытый доступSolar steam generation in fine dispersions of graphite particles(2020) Alyaev, S.; He, Y.; Kuzmenkov, D. M.; Delov, M. I.; Zeynalyan, K.; Struchalin, P. G.; Kutsenko, K. V.; B. V. Balakin.; Кузьменков, Дмитрий Михайлович; Делов, Максим Игоревич; Стручалин, Павел Геннадьевич; Куценко, Кирилл Владленович© 2020 Elsevier LtdThe direct photothermal boiling in suspensions of nano- and microscopic particles finds multiple applications in concentrated solar power: turbine-based combined heat and power (CHP) generation, solar distillation, energy storage, and chemical synthesis. However, the most promising application is solar desalination. There have been multiple studies aimed at the evaporation of suspensions using simulated solar light, but there is neither a theory describing the process nor a well-documented prototype study. This article aims at the development of an experiment and a theory, that describe the photothermal boiling in aqueous suspensions of graphite. We develop a laboratory scale steam-fluid loop with continuous condensation that recycles the water back to the process. We clarify how the concentration and incident radiant heat influence the steam generation. The optimum concentration of graphite particles - 1 wt% - was found experimentally at 17.4 suns. We studied the granulometry of the suspension and dynamics of steam bubbles. We document how the particle size distribution and bubbles evolve in boiling suspension. The theoretical description of the process is based on a heat balance analysis for an individual steam bubble. The developed model is validated against three independent experimental datasets, exhibiting accuracy with the lowest average discrepancy of 10%.

- ПубликацияОткрытый доступNumerical studies of boiling in nanofluids exposed to thermal radiation(2019) Karelova, D. G.; Kuzmenkov, D. M.; Kutsenko, K. V.; Delov, M. I.; Balakin, B. V.; Кузьменков, Дмитрий Михайлович; Куценко, Кирилл Владленович; Делов, Максим Игоревич© 2019 Author(s).Photothermal boiling in nanofluids is an energy-efficient process finding multiple promising applications in medicine, space technology, laser printing and nuclear engineering. The most important field is though solar energy where the nanoparticle-driven boiling of the base fluid drives a nano-turbine or a distillator. Hundreds of experimental and theoretical studies has been conducted in this direction over the past decade. There is however no reliable theory that describes kinetics of the process. The present contribution presents a numerical model of the process of photo-thermal evaporation in aqueous nanofluids. The model was used to predict the evaporation rate depending on concentration of the nanoparticles. The simulation results were compared with the experimental data over a range of concentrations (up to 10% wt.), demonstrating suitable agreement with the experiment.

- ПубликацияОткрытый доступEffect of External Induced Convection on Heat Transfer at Water Boiling(2021) Laouar, S.; Yanar, N.; Litvintsova, Y. E.; Kuzmenkov, D. M.; Delov, M. I.; Kutsenko, K. V.; Кузьменков, Дмитрий Михайлович; Делов, Максим Игоревич; Куценко, Кирилл Владленович© 2021, Pleiades Publishing, Ltd.Abstract: In this paper, we experimentally and theoretically study the effect of external induced convection on heat transfer from horizontal heaters under conditions of pool boiling of saturated water at atmospheric pressure. The induced convection is shown to significantly affect the heat transfer in the natural convection mode and hardly affects the heat transfer in the nucleate boiling mode. The proposed model for calculating the heat transfer coefficient at the heat transfer intensification due to external induced convection is in good agreement with the experimental data. The results of the study can be used in the design of heat exchange equipment for the needs of the nuclear power industry.

- ПубликацияОткрытый доступInfluence of Particle Size Distribution on the Optical Properties of Fine-Dispersed Suspensions(2022) Kuzmenkov, D.; Struchalin, P.; Litvintsova, Y.; Delov, M.; Skrytnyy, V.; Kutsenko, K.; Кузьменков, Дмитрий Михайлович; Стручалин, Павел Геннадьевич; Делов, Максим Игоревич; Скрытный, Владимир Ильич; Куценко, Кирилл ВладленовичNanofluids have great potential for solar energy harvesting due to their suitable optical and thermophysical properties. One of the promising applications of nanofluids is utilization in solar collectors with the direct absorption of light (DASC). The design of a DASC requires detailed knowledge of the optical properties of nanofluids, which can be significantly affected by the particle size distribution. The paper presents the method to take into account the particle size distribution when calculating nanofluid extinction spectra. To validate the proposed model, the particle size distribution and spectral absorbance were measured for aqueous suspension with multi-walled graphite nanotubes; the minimum size of primary nanoparticles was 49 nm. The proposed model is compared with experiments demonstrating the concentration averaged and maximum discrepancies of 6.6% and 32.2% against 12.6% and 77.7% for a model assuming a monosized suspension.
- ПубликацияОткрытый доступTransient boiling crisis in liquid nitrogen. influence of heater size and heating rate(2020) Delov, M. I.; Kuzmenkov, D. M.; Lavrukhin, A. A.; Kutsenko, K. V.; Делов, Максим Игоревич; Кузьменков, Дмитрий Михайлович; Лаврухин, Алексей Анатольевич; Куценко, Кирилл Владленович© 2020It is known that the nucleate boiling of different refrigerants (liquid nitrogen, freons etc.) may drop to the film boiling regime at a heat flux, which is significantly lower than the value from the standard boiling curve. This happens during unsteady heating at a minimum critical heat flux, whose value depends on different parameters of the process: heater geometry, pressure, subcooling relative to saturation, fluid type, initial conditions etc. In this article, we present new experimental results on the influence of the size of the heater and the heating rate on the minimum critical heat flux. The experiments are accompanied by numerical simulations and a theoretical analysis, where we demonstrate how the minimum critical heat flux is computed for a given case. In addition, we demonstrate that the minimum critical heat flux does not depend on the size of the heater at atmospheric pressure when the size of the heater is larger than 1 mm. This parameter is also independent of the temporal history of heat supply. The derived theoretical approach finds applications in the design of the systems based on high-temperature superconductors.
