Computation of natural convection in horizontal annular sector ducts were performed under following boundary conditions: constant higher temperature at inner tube wall, constant lower temperature at outer tube wall and the plane walls are adiabatic.
对水平放置环状扇形通道在内、外管壁为恒热、冷温度，及两侧壁为绝热的边界条件下件下自然对流换热的数值计算，得出了偏转角、扇角、半径比及Ｒａ数对当量导热系数Ｋ∞的影响，基本揭示了各种环状扇形通道内的自然对流换热规律，对工程实际应用有很强的指导意义。
