The effect of velocity and pressure distributions in wet gas metering using slotted orifice flow meter was clearly understand by fully developed a turbulent condition in the 1.6 in long horizontal pipe line equipped with slotted orifices having a 3 ratio of 0.40.

In conclusion, the numerical results indicate that pressure drop and static pressure recovery was better with the slotted orifice, and hence was preferable for wet gas metering. Moreover, with the rectangular slots, the static pressure recovery improves marginally as the aspect ratio increases. It was also found that the slotted orifice was more sensitive to wet gas flow compared to the standard orifice. 2015-01 Undergraduates Project Papers NonPeerReviewed application/pdf en http://umpir.ump.edu.my/id/eprint/12485/1/FKKSA%20-%20MUHAMMAD%20SYAZUWAN%20BIN%20NORDIN.PDF application/pdf en http://umpir.ump.edu.my/id/eprint/12485/2/FKKSA%20-%20MUHAMMAD%20SYAZUWAN%20BIN%20NORDIN%20-%20CHAP%201.PDF application/pdf en http://umpir.ump.edu.my/id/eprint/12485/3/FKKSA%20-%20MUHAMMAD%20SYAZUWAN%20BIN%20NORDIN%20-%20CHAP%203.PDF Muhammad Syazuwan, Nordin (2015) A CFD simulation study on the effect of velocity and pressure distributions in wet gas metering using slotted orifice flow.
