“…Firth and Meyer [31] conducted an experimental study of the Stanton number and pressure drop performances of four different types of artificially roughened walls. They showed the statistical data for square transverse ribbed, helically ribbed, trapezoidal transverse ribbed, and three-dimensional walls for comparison, as shown in Hosni et al [33] presented the effect of truncated cone roughness elements on the local St and f and compared the experimental data with previously reported results obtained in the same test facility under similar flow conditions. Wu and Cooper [34] explored the heat transfer and pressure drop of an SAC with hemispherical indentations as roughness elements on a heated plate.…”

“…However, since the grid sensitivity in thermal field results (not shown) is not similar to that of the flow field, making wall-adjacent cells higher than the roughness is strongly recommended to obtain reasonable thermal-field results. Hosni et al (1991) measured Stanton number St distribution in zero pressure gradient isothermally heated rough wall boundary layer flows. They arranged hemispherical roughness elements on the base of their wind tunnel.…”

“…It does not rely on definition of an equivalent sandgrain roughness. Excellent agreement between the discrete element approach predictions and experimental results has been demonstrated for heat transfer aJ_d skin friction in aerodynamic turbulent boundary layers over surfaces roughened with three-dimensional elements (Hosni et al, 1989(Hosni et al, , 1991.…”
