摘要

Practical applications of various bent pipes often show turbulent flow. This work is done to study single-phase turbulent flow of water through a Z-bend pipe. The SST k-omega turbulence model is used to simulate the flow. Prior to simulation, the method was validated with published results in previous literature, and a good agreement was established between the designed and published results. The present work establishes that the pressure and velocity contours of the Z-bend carrying water remain the same for the considered range of Reynold’s number. The mean velocity tends to move from the inner part to the outer part of both the bends. However, the location of the points of separation at the lower and upper bends varies with Reynold’s number.
