摘　　要：采用瞬态数值模拟的方法,对球罐在热处理过程中壁面温度场的分布及其变化规律进行了研究,比较了在球罐内部设置不同形式的导流伞对球罐内部流场和壁面温度场的影响。结果表明球罐在热处理过程中壁面各点的相对温度是变化的;球罐内部导流伞的设置对燃烧烟气的流场有较大的影响,合理地设置导流伞可以大幅度地提高球罐在热处理过程中壁面温度的均匀性。为球罐热处理壁面温度的均匀化研究提供了思路和方法。By using transient numerical simulation, the distribution and variation of temperature field in thickness of spheroidal tank in heat treatment were studied. The effects of different diversion umbrellas to flow field and temperature field at inside of tank were compared. It was shown that in heat treatment the temperatures at different points at inner surface are varied, and use of diversion umbrella inside of tank has relative large effect to fluid field of combustion gas so that appropriate use of diversion umbrella may greatly make homogeneity of temperature at inner surface of spheroidal tank in heat treatment. What presented herein may be used as reference in study of making homogeneity of temperature in thickness of spheroidal tank in heat treatment.
