Investigation of Convective Heat Transfer and Friction Factor in Corrugated Channels with Different Inclination Angles Using Computational Fluid Dynamics

Convective heat transfer and friction factor properties for periodic undulating channels are numerically investigated. The finite volume method (FVM) was used in the numerical study. Three different Reynolds averaged simulation (RANS) based turbulence models, shear stress transport SST k-ω transition model were compared with each other. Two used; first geometry is a sharp corrugated channel 30° inclination angle, second 45° angle. number varies range of 2000-7500. Prandtl kept constant at 0.7. Nusselt number, factor, variations good effect angle pitch discussed.
