Abstract: “In this paper, numerical study was conducted on perforated pipes with phasing angle 180 degree and 90 degree respectively. The calculation were carried out with ANSYS FLUENT 15.01 using k-E (RNG) model. It concluded from results there is no change in acceleration and frictional wall pressure between 180 degree and 90 degree perforation phasing. Total pressure drop in 90 degree perforation phasing has the highest value compared with 180 phasing angles due to intensified influence of mixing pressure drop. The decreases in additional pressure drop in 90 degree phasing has the lower value in compared to additional pressure drop at 180 degree phasing this is due to intensified influence of mixing effects pressure drop.”
