作为这次通信的主题的实验结果提供了闭管火焰形状的高速纹影图像，该形状后来被称为郁金香火焰。纹影图像以及燃烧室内的压力记录有助于证明燃烧室长度、当量比和点火器几何形状对郁金香火焰形成的影响。压力/时间记录显示出与向郁金香转变过程中火焰形状变化相关的明显特征。测量表明，基本的郁金香火焰形成是一种强健的现象，除了燃烧室的整体几何形状外，几乎不依赖于其他因素。
The experimental results that are the subject of this communication provide high-speed schlieren images of the closed-tube flame shape that has come to be known as the tulip flame. The schlieren images, along with in-chamber pressure records, help demonstrate the effects of chamber length, equivalence ratio, and igniter geometry on formation of the tulip flame. The pressure/time records show distinct features which correlate with flame shape changes during the transition to tulip. The measurements indicate that the basic tulip flame formation is a robust phenomenon that depends on little except the overall geometry of the combustion vessel.
