Abstract:

In this paper fluid flow characteristic in reduction section of a pipe system is analyzed. Two reduction sections type, known as the concentric and eccentric reducers are considered. The basic flow characteristics considered are pressure and velocity. According to Bernoulli’s theorem, these parameters (pressure and velocity) vary with respect to one another as fluid flows through reduction section in a pipe system. This variability arises because the Bernoulli’s theorem is predicated on the continuity law. The behavior of fluid in these sections is analyzed using a CFD approach. Here, the fluid flow characteristic in the two reducer types is visualized using ANSYS Fluent. The results obtained show that the flow behavior through these two sections differs slightly and the tapered angle of the reducers has significant effect on the flow behavior despite the equivalent dimension of the inlet and outlet diameters and length.
