摘　　要：矩形窄缝流道窄边附近流场和温场的分布对于优化设计宽边和窄边边角近壁区域的加热方式具有重要的意义,是设计者非常关心的问题之一。为了深入了解矩形窄缝流道内近壁区域的流场和温场的分布情况,采用商用计算流体动力学程序CFX对矩形窄缝内流场和温场进行了求解和分析,获得了矩形窄缝流道内宽窄边交界边角区域的流场和温场的分布情况,并对该区域的流场和温场及其影响因素进行了分析。Flow field and temperature field is very important for designing an optimized heated mode near the comer in a rectangular narrow channel, which is also one of the concerned problems of the deviser. To better understand the flow field and temperature field in a rectangular narrow channel, flow field and temperature field in a rectangular narrow channel were solved and analyzed. By the Computational Fluid Dynamics （CFD） code CFX, flow field and temperature field near the wall region in a rectangular narrow channel were obtained, and the effect of unheated region on flow field and temperature field was analyzed.
