In this paper, the heat transfer in liquids and nanofluids in a cylindrical tube is investigated. The exact solution for the temperature of one-component fluid (water) is obtained. Numerical simulation of forced convection of water and water/ nanofluid is performed and the temperature distribution in the tube is found. As a re: sult, the efficiency of heat transfer in water/ nanofluid is investigated depending on nanoparticle concentration and flow velocity.
В данной работе исследован теплообмен в жидкостях и наножидкостях в цилиндрической трубе. Построено точное решение для температуры однокомпонентной жидкости (вода). Выполнено численное моделирование вынужденной конвекции для воды и наножидкости вода/, построено распределение температуры в трубе. Исследована эффективность теплообмена в наножидкости вода/ в зависимости от концентрации наночастиц и скорости течения.
