Abstract

Se presenta un estudio numérico de flujo multifase realizado en un paquete comercial de CFD (Computational
Fluid Dynamics) que pretende simular el movimiento de partículas al interior de equipos de concentración gravimétrica
centrífuga (hidrociclón) y en lecho (jig) cuando se opera con suspensiones minerales de diferentes densidades
y tamaños de partícula. Se evalúa la trayectoria de las partículas, aspecto que condiciona el funcionamiento
de ambos equipos como concentradores gravitacionales.
Los resultados son claves para la comprensión de los mecanismos que rigen la separación y la eficiencia pues permiten
explicar el origen de fenómenos hidrodinámicos importantes desde la perspectiva de aplicación industrial,
una vez conocida la trayectoria.
