Experiments on the Surging of a Blower

抄録

This paper deals with experiments on surging phenomena. The results may be summarized as follows : 1. The air column in the pipe-line vibrates in a certain form resembling that of free vibration. 2. The more rapid revolutions of a blower become, the more violent the surging grows, and the more important role the characteristic of a blower plays in determining the amplitude of the surging. 3. When the length and area of a cross section of the pipe-line are fixed, the surging is apt to be built up according to the volume of the tank. 4. The feature of the surging is considerably influenced by the conditions under which the energy is dissipated from vibrating air column.
