Abstract
The discharge flow into the atmosphere is used for industrial use such as a sprinkler and a thaw system of track. For high efficiency and high precision of these systems, it is necessary to spray the same flow rate for dispersion domain. However, characteristics of discharge from side holes of a pipe have not been clarified. The purpose of the present study is to perform numerical analysis of pipe-inside flow including gas-liquid two-phase discharge flow from the side holes of the pipe and is to clarify a key factor of pipe flow with side holes.
