Numerical Investigation of Heat Transfer and Pressure Drop in a Corrugated Channel

The influence of variation in rib-height to channel-height ratio (e/H) on the heat transfer and pressure drop characteristics inside a channel with corrugated upper and lower plates was investigated numerically in the present study. The governing equations were solved by using finite volume approximations for a wide range of (0.06 < e/H < 0.26) and Reynolds numbers (5400 < Re < 23000), with a more concern on using the more adequate turbulent model. The computed results demonstrate the noticeable effects of this character on the heat transfer performance as well as the pressure drop to achieve the most effective and optimal corrugation design. In addition, RNG  turbulent model has better agreement with the experimental data.
