Abstract: “In this study, the effects of equilateral triangular bodies replaced into the channel on heat transfer and flow characteristics were examined numerically. In this research conducted numerically with RNG k-ε method, Reynolds number varied from 5.000 to 10.000. Water was used as working fluid and the constant surface temperature (360K) boundary condition was applied to the bottom wall of the channel. The effects of side length of triangular bodies and Reynolds number were investigated. At the end of the analyses, local and mean Nusselt number, local and mean surface friction factor changes and heat transfer enhancement ratios were given.”
