Abstract
Experimental data are reported on convective heat transfer and hydraulic resistance in air flows through an annular gap whose inner tube was shaped with staggered spherical recesses-cavities and through a pipe with spherical bulges. The experiments were carried out in the following ranges of flow and geometric parameters: Ref,°d = 2.103 8.103
