RÉSUMÉ

The results of theoretical and experimental investigations of heat transfer intensification by the use of spherical cavities formed on heat transfer surfaces are presented. A calculation model for determination of the heat transfer and hydraulic resistance for a turbulent flow in channels with spherical cavities in the walls is proposed.
