Description

Multicomponent flow problem is typical for a number of technologies: oil refining, natural-gas processing, food manufacturing, industrial wastewater treatment, passive mixers, lab-on-a-chip, etc..
In this benchmark we present a 3D simulation of three-component flow in cross-coupled pipes. All three components (white, red and blue) are water based solutions. Flow characteristic velocity is 2 cm/s.
