摘　　要：针对超临界水堆使用的棒束,取1根加热棒为中心的矩形区域作为研究对象,采用CFD中CFX10作为数值计算方法,研究了25 MPa超临界压力下,有无交混翼时流体的流动和传热特点。计算结果表明:交混翼可增加流道内温度分布的均匀性,同时具有强化传热作用。In order to investigate the mixing vane effect on the characteristic of flow and heat transfer under 25 MPa pressure, numerical study was performed with CFX10 in a rectangular channel with a heating rod in center of it, which was modeled from fuel bundles of supercritical water reactor. The results indicate that mixing vane has the distribution of temperature in cross section of channel more uniformly than that without it, and heat transfer is enhanced by the mixing vane.
