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: Re_f,°d = 2^.10³ 8^.10³
