摘要
建立钝体燃烧器模型,对钝体尾部回流区进行数值模拟。通过改变钝体燃烧器的空气和燃气入口速度,数值模拟轴线上速度的变化规律,并获得转换曲线。结果表明,数值模拟与实验结果能基本吻合。
Bluff body burner model is established to make numerical simulation for bluff body tail recirculation zone. Through the change of air and combustion air input speed, change pattern of speed at the axis is simulated numerically and transformation curve is acquired. The results show that the numerical simulation basically tallies with test results.
