New Method for Reducing Fluid Flow Resistance --- Gravity Pipe Flow under the action of Torricelli’s Vacuum

摘要

In this paper, firstly, the aerated pipe flow experiment is introduced. And some experimental research on comparison between different volume of air entrained is presented. Then, the technical characteristics of gravity pipe flow under the action of Torricelli's vacuum are dissertated, including creative and functional design, fundamental principle and the strange energy loss phenomena of fluid movement. In the end, an appeal in relation to the appli applied ed studies and basic theory research is given.
