Three different geometries have been used in this study, which investigated the effect of
inclination angle on convective heat transfer in corrugated channels. The corrugated channel
geometries used have inclination angles of 30°, 45°, and 60°. The finite volume method has
been used in the study with numerical methods. k-ω, SST, and transition SST have been used
as turbulence models. The mesh file used in the analysis consists of 192000 cells. The results
obtained from the calculations using a corrugated channel with a 30° inclination angle have
been compared with the experimental data. As a result of this comparison, the turbulence model
to be used for this study has been determined as SST. SST turbulence model has been used in
the analyzes made using a corrugated channel with 45° and 60° inclination angles and the results
have been compared with each other. The Reynolds number ranges from 2225 to 7380. The
Nusselt number and friction factor have been calculated using the data obtained as a result of
the analysis. Based on the calculated values, it has been determined that the heat transfer
increases as the angle of inclination increases in the corrugated channels. It has been also
observed that the Nusselt number increased as the Reynolds number increased. It has been also
seen that the analyzes for high Reynolds number gave results closer to the experimental data.
