- ПубликацияТолько метаданныеDiagnostics of transient heat transfer regimes based on statistical and frequency analysis of temperature fluctuations(2020) Delov, M. I.; Litvintsova, Y. E.; Kuzmenkov, D. M.; Laouar, S.; Maslov, Y. A.; Lavrukhin, A. A.; Balakin, B. V.; Kutsenko, K. V.; Делов, Максим Игоревич; Кузьменков, Дмитрий Михайлович; Маслов, Юрий Александрович; Лаврухин, Алексей Анатольевич; Куценко, Кирилл Владленович© 2019, © 2019 Taylor & Francis.The paper presents the results of experimental and theoretical studies of temperature fluctuations at the surface of heaters in different heat transfer regimes. Developing several methods of treatment for the temperature fluctuations, we succeed in the diagnosing the onset of transient boiling regimes. The proposed methods are based on the statistical analysis of histograms and amplitude-frequency analysis of the spectra of temperature fluctuations. In addition, the study demonstrates and compares how these techniques may be utilized to predict the transitions from the convective heat transfer to the nucleate boiling and the film boiling regimes.
- ПубликацияТолько метаданныеDiagnostics of coolant boiling onset based on the analysis of fluctuations of thermohydraulic parameters(2020) Litvintsova, Y. E.; Laouar, S.; Delov, M. I.; Kuzmenkov, D. M.; Lavrukhin, A. A.; Kutsenko, K. V.; Делов, Максим Игоревич; Кузьменков, Дмитрий Михайлович; Лаврухин, Алексей Анатольевич; Куценко, Кирилл Владленович© Published under licence by IOP Publishing Ltd.When operating heat-exchange facilities, it is of interest to develop methods of diagnostic and prediction for coolant boiling onset. It is known that the surface temperature of a heating element always has stochastic oscillations around an average value, the analysis of such fluctuations will make it possible to predict the change in the heat transfer regimes. This paper presents the results of an experimental study of temperature fluctuations for an inertial heater and using of method of diagnostic are based on statistical and frequency analysis of temperature fluctuations. It is shown that there is a correlation between the frequency characteristics of heater temperature fluctuations and oscillations in the thermohydraulic parameters of the coolant (temperature, flow, pressure). The obtained results will find application in the development of an automated system for diagnostics the coolant boiling onset in power facilities.
- ПубликацияТолько метаданныеA thermohydraulic flow loop for developing novel solutions in the field of using digital twins for nuclear power facilities(2020) Laouar, S.; Delov, M. I.; Litvintsova, Yu. E.; Kuzmenkov, D. M.; Muradyan, K. Yu.; Navasardyan, M. V.; Kutsenko, K. V.; Делов, Максим Игоревич; Кузьменков, Дмитрий Михайлович; Мурадян, Карен Юрикович; Куценко, Кирилл Владленович© 2020 Obninsk Institute for Nuclear Power Engineering, National Research Nuclear University 'MEPhI'. All rights reserved.The experience is presented in building a thermohydraulic flow loop for developing technical and software solutions in using digital twins of nuclear equipment. The thermohydraulic flow loop was developed and manufactured at National Research Nuclear University MEPhI and represents a two-loop facility that allows investigating the processes of heat and mass exchange at forced and natural water circulation modes. The experimental facility allows one to obtain new data on heat transfer and hydrodynamics of two-phase flows round the fuel element bundles required for verification of computer codes. The obtained preliminary experimental results agree well with the calculations based on various codes. As part of building a digital twin for the thermohydraulic flow loop, a system is developed to diagnose, control and monitor heat-exchange transients based on physically justified real-time techniques. Neural network technologies will make it possible to predict changes in the flow loop's thermohydraulic parameters in response to external impacts. Further, a virtual prototype of the experimental facility is expected to be used in the training process and for distance learning.
- ПубликацияТолько метаданныеSolar 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%.
- ПубликацияТолько метаданныеNumerical 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.
- ПубликацияТолько метаданныеPerformance of a tubular direct absorption solar collector with a carbon-based nanofluid(2021) Nikolaev, O. V.; Vologzhannikova, A. A.; Shevelyova, M. P.; Gorbacheva, O. S.; Struchalin, P. G.; Yunin, V. S.; Kutsenko, K. V.; Balakin, B. V.; Стручалин, Павел Геннадьевич; Куценко, Кирилл Владленович© 2021 Elsevier LtdDirect absorption solar collectors (DASC) with nanofluid represent a new direction in solar thermal technology that is simpler yet more efficient than conventional equipment. In this work, we report details of performance for a custom tubular DASC with a carbon-based nanofluid. The collector was tested experimentally following a standard procedure and using a multiphase CFD-model of the device. The experiments were carried out in a range of flow rates 2. 10 l/min, nanoparticle concentrations 0.0015. 0.082%wt., temperature differences (up to 29.3 degrees), and radiant heat fluxes. We found that, at a particle concentration of 0.01%, the collector demonstrated the average thermal efficiency of 80%. For the comparable temperature differences, the efficiency of DASC was 5.8. 37.9% higher than a collector with similar geometry but a surface absorption of light energy. The CFD-model, validated against our experiments, depicts flow patterns in the DASC focusing on nanoparticles’ deposition. Less than 5% of particles deposit under local flow restrictions at flows above 6 l/min. The deposition patterns from the CFD-model correlate to the experimental observations.
- ПубликацияТолько метаданныеInfluence 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.
- ПубликацияТолько метаданныеDirect absorption solar collector with magnetic nanofluid: CFD model and parametric analysis(2019) Zhdaneev, O. V.; Kosinska, A.; Balakin, B. V.; Kutsenko, K. V.; Куценко, Кирилл Владленович© 2018 Elsevier Ltd Direct absorption collectors (DAC) with nanofluid are among the most promising yet least studied in solar energy technology. There are numerous micro- and macroscopic factors that determine their efficiency. This complicates in situ optimization of DACs using physical prototypes. The present paper describes a multiphase CFD model of the collector, which was validated against two independent experimental datasets. The model was used for a multiparametric numerical analysis, where we altered concentration and size of the nanoparticles, as well as the geometry and inclination of the collector. The optimization resulted in up to 10% improvement in the collector's efficiency. Finally, we considered the process of thermomagnetic convection in the collector using a magnetic nanofluid. This resulted in a 30% increase in the collector performance.
