В работе экспериментально исследовано влияние гибридной дисперсной фазы TiO2-Al2O3 на теплопроводность λ(T) и кинематическую вязкость 𝜈 (T) наномасел на основе оливкового и подсолнечного масел. Наномасла получали двухэтапным методом при суммарной концентрации твёрдой фазы 2 vol.% с ультразвуковой гомогенизацией; теплопроводность измеряли анализатором TEMPOS, а кинематическую вязкость определяли капиллярной вискозиметрией (ВПЖ-2) в диапазоне 20-50 °C (293-323 K). Установлено, что для базовых масел ν закономерно уменьшается с повышением температуры, тогда как введение TiO2-Al2O3 приводит к росту кинематической вязкости на 17,5% по сравнению с соответствующими базовыми маслами во всём диапазоне температур. Теплопроводность базовых масел изменяется слабо и демонстрирует умеренное снижение при нагреве, а добавление TiO2-Al2O3 повышает λ на 5%. Полученные зависимости λ(T) и 𝜈(T) могут быть использованы для обоснования выбора состава наномасла с учётом баланса усиления теплопереноса и роста гидравлических потерь.</p></abstract><trans-abstract xml:lang="en"><p>Vegetable oils are considered promising base fluids for nanolubricants; however, their practical application is governed by the trade-off between enhanced thermal conductivity and increased viscous losses. In this work, the effect of a hybrid dispersed phase TiO2-Al2O3 on the thermal conductivity λ(T) and kinematic viscosity ν(T) of nanolubricants based on olive and sunflower oils was experimentally investigated. The nanolubricants were prepared by a two-step method at a total solid-phase concentration of 2 vol.% with ultrasonic homogenization; thermal conductivity was measured using a TEMPOS analyzer, and kinematic viscosity was determined by capillary viscometry (VPZh-2) over the temperature range of 20-50°C (293-323 K). It was found that for the base oils, ν decreases monotonically with increasing temperature, whereas the addition of TiO2-Al2O3 increases the kinematic viscosity by 17,5% relative to the corresponding base oils across the entire temperature range. The thermal conductivity of the base oils varies only slightly and exhibits a moderate decrease upon heating, while the incorporation of TiO2-Al2O3 increases λ by 5%. The obtained λ(T) and ν(T) relationships can be used to substantiate the selection of nanolubricant composition by accounting for the balance between heat-transfer enhancement and the rise in hydraulic losses.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>растительные масла</kwd><kwd>наномасло</kwd><kwd>гибридные наночастицы</kwd><kwd>TiO2</kwd><kwd>Al2O3</kwd><kwd>теплофизические свойства</kwd><kwd>температурная зависимость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vegetable oils</kwd><kwd>nanolubricant</kwd><kwd>hybrid nanoparticles</kwd><kwd>TiO2</kwd><kwd>Al2O3</kwd><kwd>thermophysical properties</kwd><kwd>temperature dependence</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данное исследование финансируется Комитетом науки Мини</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Thermal Conductivity Characterization of High Oleic Vegetable Oils Based Hybrid Nanofluids Formulated Using GnP, TiO2, MoS2, Al2O3 Nanoparticles for MQL Machining / A.C.
