Наножидкости, состоящие из наночастиц, диспергированных в базовой жидкости, представляют значительный интерес из-за их улучшенных тепловых характеристик по сравнению с традиционными жидкостями. В исследовании используется аддитивный метод – широко используемый метод оценки эффективной теплоемкости наножидкостей. Этот метод подразумевает, что общую теплоемкость наножидкости можно аппроксимировать путем суммирования вкладов каждого компонента в соответствии с его объемом или массовой долей. Данное исследование представляет влияние концентрации наночастиц (1 мас.%, 3 мас.%, 5 мас.%) на эффективную теплоемкость наножидкости на основе TiO2. Анализ показывает, что ключевыми факторами, влияющими на теплоемкость наножидкости, определенную аддитивным методом, являются теплоемкость отдельных компонентов и концентрация наночастиц. В частности, чем больше разница в теплоемкостях между базовой жидкостью и наночастицами и чем выше концентрация наночастиц, тем больше теплоемкость наножидкости смещается в сторону теплоемкости наночастиц. Расчеты в данной работе показывают, что наиболее существенное снижение теплоемкости происходит в наножидкости, содержащей 5 мас.% наночастиц Al2O3, с водой в качестве базовой жидкости. Напротив, наименьшее снижение наблюдается в наножидкости с 1 масс.% наночастиц Al2O3 в 50% водном растворе этиленгликоля.</p></abstract><trans-abstract xml:lang="en"><p>This study investigates the thermal properties of nanofluids, with a particular focus on their heat capacity when various nanoparticles are integrated into a base fluid. Nanofluids, which are composed of nanoparticles dispersed within a base fluid, are of significant interest due to their enhanced thermal characteristics compared to traditional fluids. The research employs the additive method, a widely used technique for estimating the effective heat capacity of nanofluids. This method posits that the total heat capacity of a nanofluid can be approximated by summing the contributions of each component according to its volume or mass fraction. This research represents the effect of nanopartilces concentration (1wt.%, 3 wt.%, 5 wt.%) on effective heat capacity of TiO2 based nanofluid. The analysis reveals that key factors influencing the heat capacity of a nanofluid, as determined by the additive method, include the heat capacities of the individual components and the concentration of the nanoparticles. Specifically, the greater the disparity in heat capacities between the base fluid and the nanoparticles, and the higher the nanoparticle concentration, the more the nanofluid's heat capacity shifts toward that of the nanoparticles. The calculations in this study indicate that the most significant decrease in heat capacity occurs in a nanofluid containing 5 wt.% Al2O3 nanoparticles with water as the base fluid. Conversely, the smallest reduction is observed in a nanofluid with 1 wt.% Al2O3 nanoparticles in a 50% aqueous ethylene glycol solution. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>наножидкость</kwd><kwd>удельная теплоемкость</kwd><kwd>теплофизические свойства</kwd><kwd>наночастицы</kwd><kwd>теплообмен</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nanofluid</kwd><kwd>specific heat capacity</kwd><kwd>thermophysical properties</kwd><kwd>nanoparticles</kwd><kwd>heat transfer</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Choi S.
