从研究火焰的传播速度出发,在大气压条件下,利用高压发生器,探讨了1万2千伏直流高压电场对火焰形状及传播速度的影响。实验测定了电场对本生灯和玻璃管内火焰形状的影响。并对焰传播速度的改变作了测量计算。两种装置的实验结果表明:对本生灯火焰形状有明显影响,对管中火焰速度有不同程度的改变。文中从高压电场产生的离子风角度对实验结果作了浅析。
Based on the study of propagation velocity of flame, the influence of the 12,000-volt HVDC electric field on the shape and propagation velocity of flame was discussed under high pressure at atmospheric pressure. The influence of electric field on the shape of flame in Bunsen burner and glass tube was experimentally determined. The flame propagation velocity was measured and calculated. The experimental results of the two devices show that the flame shape of the Bunsen burner has a significant effect on the flame speed in the pipe to varying degrees of change. The paper analyzes the experimental results from the angle of ion wind generated by high-voltage electric field.
