Flow Visualization of Branch Region of Duct Line

Abstract

The aim of this research is to rationalize the prouduction methods of the duct branch and the investigation was performed at the point of loss of branch.
Six kinds of branch type were used for the testand the flow rate of the branched flow to the main flow was set to 1/2.
The pressure distributions along the flow direction were measured using Pitot tubes and inclined manometer.
The results of these research shows that the branch Type2 is fitted to the purpose of rationalization.
