研究了离心加速度对本生灯稳定火焰形态和稳定性的影响。结果表明，随着旋转角速度的增大，经典本生锥首先在尖端发生轻微的屈曲。屈曲变得更加突出，最终火焰进入燃烧器。在足够快的旋转，火焰稳定的燃烧器边缘变得不可能和火焰闪光回来。理论结果与在旋转本生灯上的实验观察结果吻合良好。
The influence of centrifugal acceleration on the form and stability of the Bunsen burner stabilized flame is studied. It is shown that as the angular velocity of rotation increases, the classical Bunsen cone first slightly buckles at the tip. Buckling then becomes more prominent, and eventually the flame enters the burner. At sufficiently rapid rotation, flame stabilization by the burner rim becomes impossible and the flame flashes back. The theoretical findings are in favorable agreement with the experimental observations made on a rotating Bunsen burner.
