| 中文摘要: |
| 运用Ansys里的Fluent模块功能,从流体初始速度、蓄热体结构数值以及换向周期等几个因素对其换热性能的影响进行了数值模拟,可得到蓄热室内部和面壁在蓄热和冷却期间的温度云图。研究表明(1)蓄热体换热过程中温度随时间变化的规律；(2)运用数值分析的方法对蓄热室内部从初始状态到稳态工作过程进行了模拟,得到并分析了在工作运行中烟气和空气出口温度的改变状况；(3)分析稳态时的加热和冷却末期时间段蓄热体内部温度情况。可以在接下来的研究换热机制中奠定良好的基础。 |

| Using the function of the Fluent module in Ansys, the effects of several factors such as the initial velocity of the fluid, the value of the heat storage structure and the commutation period on its heat transfer performance were numerically simulated. Temperature cloud during cooling. The research shows that (1) the law of temperature change with time during the heat storage process of heat storage body; (2) The numerical analysis method is used to simulate the working process from the initial state to the steady state inside the heat storage chamber, and the working Flue gas and air outlet temperature changes during operation; (3) Analyze the internal temperature of the regenerator during the final period of heating and cooling at steady state. It can lay a good foundation in the following research on heat exchange mechanism. |
