Abstract :This paper investigates how heat transfer and fluid flow are affected by channel width as it is varied from small to large scale in a wavy sinusoidal channel. The mean Nusselt numbers in periodic fully developed regimes depend on the maximum Nusselt number at the reattachment point of the flow separated from the top of the peak, and achieve maximum at P/H=2.0~1.6 (P : pitch, H : width) ; the friction factor, on the other hand, is maximum at the same ratio P/H=2.0~1.6. The performance ratio η_<II>, at equal pumping power, attains a maximum at P/H=2.29~2.0. Thus, it can be concluded that the channel is optimum at P/H=2.0 for augmenting heat transfer.
