ANALISIS ALIRAN FLUIDA DUA FASE (UDARA-AIR) MELALUI BELOKAN 45 DERAJAT
ABSTRACT: The phenomenon of
two phase flow can be foundin our nature, at the living bodyand industrial of
the world. The flow of Fluid throughthe pipe bendshave a valuegreater than
thepressure dropstraight pipeit’s was because the changes
ingeometryandtrajectorythathave an impact onthe changeof flowpattern. This
research aims to determine of theflowpatternandtwo-phase flowpressure dropthat
occursthrough the 45° elbowfrom the horizontalto theverticalslopes upward.
Diameter ofthepipe(D) 26.64mm, variationsthatdoaregasflow rate(Q ) (1 - 3)
LPMandgasvolumefraction (β) (25 - 50) %. From theresults ofthis research we can
concludedthat theflowpattern thatoccursisthe slug/plugflowwhere the greaterthe
gasvolumefraction (β), the size of theslug/plugflowgreaterandinversely
proportional to thepressure dropfurtherdown. Upheaval of two-phase flow
patterns due to the influence of gravity occurs at the actual speed ratio of
air and water (v ) at 1 LPM air 0.713 and 0.966 at 3 LPM air. The
highestpressure dropoccurswiththe condition ofthe gasvolumefraction (β) of 50
%, actual speed ratio of air and water(v G /v L ) 0.764at107.415 Pa in
theoretically and 214.616Paat experimentally.
