COMPUTATIONAL FLUID DYNAMICS ANALYSIS OF JET-INDUCED MIXING IN A CYLINDRICAL TANK

Abstract

This project investigates the fluid mixing behavior inside a cylindrical tank using Computational Fluid Dynamics (CFD). The study focuses on how a jet inlet influences circulation patterns, velocity distribution, and overall mixing efficiency. A 3D model of the tank was constructed in SimFlow, which is a CFD software, and multiple inlet angles were simulated to determine how jet orientation affects turbulence generation and bulk fluid motion. Velocity fields, vorticity structures, and mixing time estimates were compared across configurations. The results show that inlet angle strongly influences flow symmetry and energy dissipation, with certain orientations producing significantly more effective mixing. This work demonstrates the usefulness of CFD as a predictive tool for optimizing industrial and laboratory mixing processes.
