STIR TANK/MIXING TANK FLOW SIMULATION · 模型 2675
This project features a comprehensive 3D CAD design and an advanced transient Computational Fluid Dynamics (CFD) simulation of an industrial-grade Stirred Tank Reactor, fully modeled and analyzed within SOLIDWORKS Premium 2023. The primary focus of this engineering study is to evaluate the fluid dynamics, mixing efficiency, and mechanical power requirements during a standard blending cycle. The geometric configuration utilizes a dished-bottom cylindrical tank integrated with a standard wall-mounted baffle system. These baffles play a critical role in the process by transforming tangential swirling flow into a strong axial turnover, which drastically suppresses vortex formation and eliminates potential fluid stagnation or "dead zones" at the outer corners of the vessel. At the core of the mixing mechanism is a multi-blade pitched impeller designed to maximize axial flow and drive robust macro-mixing throughout the entire fluid domain. The simulation methodology employs a time-dependent, transient approach to precisely capture the evolving nature of fluid interactions and the progression of the mixing cycle over time. By utilizing the Sliding Mesh and Rotating Region technique, a localized rotating fluid domain was established around the impeller shaft to accurately mimic real-world mechanical rotation. To track the blending progression, a multi-fluid volume fraction method was implemented to visualize the interface and dispersion rate between standard water and a secondary phase of dyed water. The computational domain was resolved using an optimized Cartesian global mesh, featuring targeted local refinement zones around the high-velocity gradients near the impeller blades and baffle walls to ensure high numerical accuracy.
