摘　　要：以蜂窝陶瓷蓄热室中流动的气体和蓄热体为研究对象,基于Fluent软件对气体在蓄热室中的流动进行仿真。在模型中均匀地采取12个监测点,采用k-epsilon RNG湍流模型和DO辐射模型,分析了工作过程中蓄热室内温度的分布与变化规律。结果得出:气体进入蓄热室后其等温线呈抛物线形状分布;在蓄热室长度方向上,加热期时离热端越近的位置温度上升速率越快,冷却期时离冷端越近的位置温度下降速率越快;在蓄热室横截面方向上,远离气体入口的位置其温度上升速率及下降速率均低于靠近气体入口的位置,且蓄热室横截面上距离气体入口不同距离的点所能达到的最高温度有较大差异。Taking the gas flowing in the honeycomb ceramic regenerator and the regenerator as the research object,based on Fluent software to simulate the gas flow in the regenerator.Take 12 monitoring points evenly in the model,adopt k-epsilon RNG turbulence model and DO radiation model,analyzed the distribution and change law of temperature in the regenerator during work.The result is:after the gas enters the regenerator,its isotherm is distributed in a parabolic shape;in the length direction of the regenerator,during the heating period,the closer to the hot end,the faster the temperature rise rate,during the cooling period,the closer to the cold end,the faster the temperature drop rate;in the crosssectional direction of the regenerator,the temperature rise and fall rates far away from the gas inlet are lower than those close to the gas inlet,and there is a big difference in the maximum temperature that can be reached at points at different distances from the gas inlet on the cross section of the regenerator.
