Исследования проводились на экспериментальной установке, содержащей турбокомпрессор, выходные каналы разной конфигурации, измерительную базу и систему сбора данных. Установлено, что стабилизация потока в выходном канале компрессора приводит к существенному росту интенсивности теплоотдачи (вплоть до 25 %) по сравнению с базовым трубопроводом при одновременном уменьшении степени турбулентности на величину до 30 %. В выходном канале компрессора с канавками наблюдается еще более существенный рост интенсивности теплоотдачи (вплоть до 30 %) при увеличении степени турбулентности на величину до 12 % по сравнению базовым каналом. Предлагаемые конфигурации выходных каналов компрессора могут быть использованы для интенсификации теплообмена с целью естественного охлаждения воздуха в процессе впуска, а также для стабилизации газодинамических параметров потока с целью снижения гидравлического сопротивления впускной системы двигателя с турбонаддувом.</p></abstract><trans-abstract xml:lang="en"><p>It is known that the thermal and mechanical characteristics of the air flow in the output channel of the turbocharger compressor largely determine the efficiency and quality of the gas exchange processes of the piston engine. The research was carried out on an experimental installation containing a turbocharger, output channels of different configurations, a measurement database and a data collection system. It was found that the stabilization of the flow in the output channel of the compressor leads to a significant increase in the heat transfer intensity (up to 25 %) compared to the base pipeline, while reducing the degree of turbulence by up to 30 %. In the output channel of the compressor with grooves, there is an even more significant increase in the heat transfer intensity (up to 30 %) with an increase in the degree of turbulence by up to 12% compared to the base channel. The proposed configurations of the compressor output channels can be used to intensify heat exchange in order to naturally cool the air during the intake process, as well as to stabilize the gas dynamic parameters of the flow in order to reduce the hydraulic resistance of the intake system of the turbocharged engine.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>турбокомпрессор</kwd><kwd>газовые потоки</kwd><kwd>выходной канал</kwd><kwd>газодинамика</kwd><kwd>степень турбулентности</kwd><kwd>локальный коэффициент теплоотдачи</kwd></kwd-group><kwd-group xml:lang="en"><kwd>turbocharger</kwd><kwd>gas flows</kwd><kwd>output channel</kwd><kwd>gas dynamics</kwd><kwd>turbulence degree</kwd><kwd>local heat transfer coefficient</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа, по результатам которой написана статья, выполнена при поддержке РНФ в рамках научного проекта 18-79-10003.</funding-statement><funding-statement xml:lang="en">the work has been supported by the Russian Science Foundation (grant No. 18-79-10003).</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">Ferguson C.R., Kirkpatrick A.T.
