摘要：The objective of this research work is to understand the behavior of water flow 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 children in the changes of the geometry. The energy losses derived from the pipes. Calculation of the cases: the occurrences of the incidents in the geometry on the part of the student and also with the help of the ANSYS software fluently. Calculations were used using the K-epsilon model. This simulation provides the values of pressure, velocity and kinetic turbulence in several sections of the pipe where water is its flow.
