摘　　要：针对高效灶具设计和优化过程中打样试验周期长、成本高的问题,结合实验和模拟方法,以一款嵌入式灶具燃烧器为例,计算火焰的流场与温度场分布以及标准锅的热效率.经实验验证,数值模拟计算的热效率在误差允许的范围内具有准确性.通过对灶具进行结构优化,增大内圈下部火孔与水平方向夹角,由0°增加至30°,减小锅支架高度,由35mm减小至25mm.模拟结果显示:对于标准下限锅,灶具整体热效率由55.3%提升至68.1%.In view of the issues on the long cycle and high cost in the samples testing process of energy saving stoves design and optimization,the Fluent was used to calculate the flow field and temperature field distribution of the stove flame and the thermal efficiency of the standard pot.Compared with the experimental data,it was verified that the thermal efficiency of the numerical simulation was within the allowable range of the error.The structure of the stove used in the simulation was optimized.The angle between the inner hole and the horizontal direction of the inner ring was increased from 0°to 30°,and the loading height was decreased from 35 mm to 25 mm.Simulation results show that overall thermal efficiency of the stove increased from 55.3%to 68.1%for the lower limit of the pot.
