Дано опи­сание устройства и принципа работы концентрирующего параболического солнечного коллектора. Выполнены расчетные исследования процессов теплообмена однофазным методом при ламинарном и турбулентном течении теплоносителей в гладкой поглощающей трубке и трубке с проволочным спиральным турбулизатором. В качестве теплоносителя использовалась чистая вода и наножидкость на основе воды с наночастицами Al2O3 объемной концентрацией 1 %. Размер наночастиц Al2O3 —50 нм. Проведен анализ влияния применения проволочного спирального турбулизатора в солнечном коллекторе в комбинации с наножидкостью в качестве теплоносителя на температурное распределе­ние в поглощающей трубке.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the main mathematical models for numerical simulation of heat transfer processes occurring in a nanofluid — single-phase and two-phase models. A description of the device and the principle of operation of a concentrating parabolic solar collector are demonstrated. The authors perform computational studies of heat transfer processes using the single-phase method with laminar and turbulent flow of heat transfer fluids in a smooth absorbing tube and a tube with a spiral turbulator wire. Pure water and a water-based nanofluid with Al2O3 nanoparticles with a volume concentration of 1 % are used as the heat transfer fluid. The size of Al2O3 nanoparticles is 50 nm. The research analyses the effect of using a spiral wire turbulator in a solar collector in combination with a nanofluid as a heat transfer fluid on the temperature distribution in the absorption tube.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>наножидкость</kwd><kwd>концентрирующий</kwd><kwd>параболический</kwd><kwd>солнечный коллектор</kwd><kwd>одно­фазная модель</kwd><kwd>двухфазная модель</kwd><kwd>турбулизатор.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nanofluid</kwd><kwd>concentrating</kwd><kwd>parabolic</kwd><kwd>solar collector</kwd><kwd>single-phase model</kwd><kwd>two-phase model</kwd><kwd>turbulator.</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">Slobodina E.
