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_, 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., 論文}, pages = {1400--1405}, title = {正弦状波形流路内の熱伝達促進におよぼす流路幅の影響}, volume = {54}, year = {1988} }
