摘要
为解决大火力小底壳灶具脉冲点火器温升问题,采用Realizablek-e湍流模型、DO辐射模型、Couple算法模拟仿真与实验测试相结合的方法,设计多种方案如调整脉冲点火器安装位置、增加挡板、增加散热孔来研究分析各情况下脉冲点火器的温升。脉冲点火器位置下移后,平均温度升高2℃;增加挡板后,平均温度降低2℃;增加开孔后脉冲点火器的温度有微小降低,不如增加挡板效果明显。左侧引射管距离脉冲点火器相较于右侧更近,使脉冲点火器左侧壁温度高于右侧壁温度。
To solve the temperature rise problem of the pulse igniter with large firepower and small bottom shell stove,this study adopts a combination of Realizable k-e turbulence model,DO radiation model,and Couple algorithm simulation with experimental test methods,and designs various solutions to study and analyze the pulse igniter temperature rise under various conditions,such as adjusting the installation position of the pulse igniter,adding baffles,and adding heat dissipation holes.The position of the pulse igniter moves downwards caused the average temperature increase by 2℃;add baffles caused the average temperature decrease by 2℃;The temperature of the pulse igniter slightly decreases after increasing the opening,which is not as effective as adding a baffle.The left ejector tube is closer to the pulse igniter compared to the right,causing the temperature of the left wall of the pulse igniter is higher than that of the right wall.
