| ABSTRACT This study examines the flow of water and air in a cross junction by fluent under Ansys 12. Initially the problem will solve by using the less computationally intensive mixture model, and then turn to the more accurate Eulerian model. In this study which is using flow of water and air inside closed and vertical conduit as cross junction so the flow is water and air as mixture in inlet of pipe and the mixture leaves the pipe in three outlets as shown in Figure (1), also the phase of the air is assume to be bubble flow, so the diameter of the bubble of air will be present. The slip velocity equation need to solve since there will be significant difference in velocities for the different phases. The study used solid work programme to work the figure and then export it to fluent of Ansys. The study used the mixture model and Eulerian model to investigate the distribution of air inside the cross pipe and the where of the effect of static pressure inside the cross conduit for design. Also the contour of velocity magnitude is used to know the moving and distribution of the flow. The comparison between the two model are happen to know the range of converge for results for two model | ||
