Abstract

Recently, CFD has offered a technological solution for modelling multi-phase flow in which we can make endless simulations with reduced expenses and effort in high accuracy results; we shall also mention that experimental studies have limitations for safety considerations when experimenting with flow in high temperature or pressure values or medium nature as in nuclear or chemical flows.In this paper, we used the ANSYS FLUENT CFD program to simulate the two-phase flow in a pipe to study the effect of attaching a 90-degree elbow fitting to the piping system, seeking to find out the change in the pattern and resulting phenomena as its impact in the pressure and velocities in the piping system also a brief of modelling methodology and main governing equations will be illustrated during the study.We used an Air-water model with different inlet velocities and operating conditions as variants, which made four simulations in other conditions. Then, we get precise results and the phenomenon of each case with its illustrations shown in the results section as contours of volume fraction, pressure distribution, and velocity fields. Finally, the conclusion section mentions the summarized results of this study.
