中文摘要：
采用曲线坐标系下压力与速度耦合SIMPLER算法，数值研究了一种波纹通道内周期性充分发展的稳态层流流动与换热情况，流动Re数的范围为20-500，Pr数为0．7．计算考察了不同Re数、纵宽比γ及纵横比φ对换热与阻力的影响．计算结果表明，Re数、纵宽比γ及纵横比φ较小时流体不出现任何回流；整体Nu数及皿数随着Re数，纵宽比γ及纵横比φ的增加而增加，换热增强，但同时流动阻力增加．其计算结果可为波纹通道的设计提供参考依据．
英文摘要：
Periodically fully developed convective heat transfer characteristics in a two-dlmensional wavy channel are investigated numerically with a constant wall temperature. The calculations are performed with Pr = 0.7, Re = 20 - 500 on non-orthogonal non-staggered grids generated by an elliptic equation system. A semi-implicit method for pressure linked equations revised （SIMPLER） algorithm in curvilinear body-fitted coordinates is employed. Effects of Reynolds number and geometric parameters, such as aspect ratio φ and shape ratio γ, on heat transfer and friction factor are studied. It shows that no recirculation region occurs through the whole channel at low Reynolds numbers, small aspect ratio or small shape ratio. With the increase of Reynolds number, aspect ratio or shape ratio, heat transfer is enhanced due to flow recirculation. Corresponding friction factor increases simultaneously.
