Numerical analysis of the speed profiles of a water flow through a gradual reduction pipe. Enfoque UTE [online]. 2018, vol.9, n.3, pp.80-92.

The objective of this research work is to understand the flow behavior of water through gradual contraction. Computational fluid dynamics (CFD) is a useful approach to solve the equations that describe the movement of fluids, using numerical methods and computational techniques; this area of ​​mechanics provides the fundamentals of pipe hydraulics and channel hydraulics. A study of the flow through the pipeline has been made to calculate the losses in the geometry changes. The energy losses due to the transverse change of the area, is an important part to analyze the flow through the pipes. The velocity profiles were determined due to the change of section in the piping systems. Calculations were used using the K-epsilon software model. This simulation provides the values ​​of the contours of pressure, velocity and kinetic turbulence in several sections of the pipe where the water is the fluid.
