Abstract
El presente trabajo aborda el problema mediante el estudio de simulaciones numérica en ANSYS Fluent, utilizando el modelo de turbulencia SSTk- omega. Se estudia la caída de presión del agua y el comportamiento del fluido bajo régimen turbulento al pasar por un sistema reductor de presión, acotado a solamente dos placas o una cámara de disipación, utilizando diferentes configuraciones para el dominio del reductor con el fin de encontrar diseños que mejoren la eficiencia de este. Las mejoras que se quieren lograr son: reducir la distancia entre las placas del reductor y encontrar una configuración en la excentricidad de los orificios de restricción de las placas, que logren optimizar la caída de presión que otorga el reductor.
The present work addresses the problem through the study of numerical simulationsin ANSYS Fluent using the SSTk-w omega turbulence model. The water pressure dropand the behavior of the fluid under turbulent regime when passing through a pressurereducing system is studied and limited to only two plates or a dissipation chamber,IVusing different configurations for the domain of the reducer in order to find designs thatimprove the efficiency of this. This work is intended to achieve improvements in theorder of reducing the distance between the reducer plates and finding a configuration inthe eccentricity of the restriction holes of the plates, which optimize the pressure dropgiven by the reducer.
