| 内容記述 | We investigate corrugated wall channels as a means of augmenting forced-convection heat transfer with single phase flow in heat exchangers. As the corrugated wall channels have simple structure and have direct effects on heat transfer due to heat transfer surface itself being bent, they are expected to have wide applications. Besides, as they can disturb the main current, they have extreme effects for the heat transfer augmentations. In order to find out adequate configurations of them, considering the model of parallel channel bent two times and that bent many times, we examine analytically and experimentally the fluid flow states and heat transfer characteristics of laminar flow and turbulent flow for various values of pitch P and bending angle θ, and try to make clear the mechanism of heat transfer augmentation. Particularly, we show aspects of flow such as impingement, deflection, separation, reattachment etc., local Nusselt number distributions, pressure losses and mean Nusselt number, indicate the effects of pitch and bending angle on them, and estimate the performance of corrugated wall channel as heat exchanger by area or volume goodness factors. | |||||
