Abstract

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.
