空気混入水平輸送における2次空気の効果に関する研究

抄録

The purpose of this research is to investigate effect of compressed secondary air injection and flow resistance in horizontal pipe flow transport system by compressed air. This transport system is very useful for high-density slurry transport because it is easily to separating air from slurry. This paper describe about the mechanism of slurry transporting system using a compressed air in the experimentally. In the experiment, the airliquid two-phase flows have been focused on liquid of low viscosity in long distance pipelines with narrow diameter and discussed the effect of secondary air and relation between air-injection volume and friction loss. As the results of experiments it was shown that the secondary air injection is useful for acceleration of slug velocity in horizontal pipe flow.
