Experimental Study of Scouring Pattern Due to Orifice Submerged Jets
In this article, downstream scour patterns were investigated for submerged jets with different diameters and shapes (circular, rectangle, diamond and square) for single jets and also effects of different angles of crossing compound jets. For this aim, all effective parameters of submerged jets behav...

| description | In this article, downstream scour patterns were investigated for submerged jets with different diameters and shapes (circular, rectangle, diamond and square) for single jets and also effects of different angles of crossing compound jets. For this aim, all effective parameters of submerged jets behavior were studied and the effective dimensionless relationships were derived according to dimensional analysis. In order to analyze this relationship, a physical model was built in KWPA laboratory and tests were run with different discharges. Then dimensions of scour patterns were measured in downstream of jets. The results indicated that the best development in pattern of scour belongs to diamond jet with average of 22% increasing in comparison by rectangle jet and the minimum of outer diameter with average of 183% increasing in comparison by the maximum one, also threefold increasing of crossing jets angles cause 58% increasing in the parameters of scour. |
