Effect of Pipe Configurations on Air Entrainment into a Louvered Cylindrical Pipe: A Comparison between Open and Close Entrance of a Pipe

The present numerical study was performed by solving conservation equations of mass, momentum and energy along with two equation based k-ε model for a louvered horizontal cylindrical pipe by finite volume method. It was found that pipe air suction increased with increase in opening area and number of nozzles for both pipe configurations. Increasing the pipe diameter made air suction more effective in pipe configuration B (open entrance of the pipe).
