Abstract(es_ES)

This work presents the study of the flow distribution in a crude oil storage tank of 36.5 m of diameter.  The tank is equipped with two side-entry impellers
placed at 90° and 45° mounting angle. Computational fluid dynamics (CFD) is used to simulate the tank conditions with 7.7 m of filling level. In addition, it is performed a homogenization time analysis of two different crude oils, for the case of mounting angle of 45°. A twophase model (Volume of fluid, VOF) is used to simulate the mixing process. The rotation of the impellers is modeling by Multiple Frames of Reference (MFR). The phenomenon is resolved using the RNG version of the k-ε turbulence model.

Keywords(es_ES)

En este artículo se presenta el estudio de la distribución del flujo en un tanque de almacenamiento de crudo de 36.5 m de diámetro. El tanque está equipado con dos agitadores mecánicos de entrada lateral ubicados a 90° y 45° de ángulo de montaje. Se emplea la dinámica computacional de fluidos (CFD) para simular las condiciones del tanque a 7.7 m de altura de llenado. Adicionalmente, se realiza el análisis del tiempo de homogenización de dos crudos de diferentes propiedades para el caso de los agitadores a 45°. Se emplea el modelo de dos fases (Volume of fluid, VOF) para el proceso de mezclado, la rotación de los agitadores se simula con múltiples marcos  de  referencia  (MFR)  y  se  resuelve  el fenómeno  utilizando  la  versión  RNG  del modelo  de  turbulencia k-ε.
