VisiMix Forum –Chemical Reaction Simulation under Mixing in Stirred Vessels
Presentation Abstract
Register here to join or receive a copy of the webinar! VisiMix Chem is designed for the simulation of stirred chemical reactors operating in the turbulent flow regime. The software utilizes the advanced hydrodynamic models implemented in VisiMix Turbulent to simulate the mixing phenomena that govern reactor performance. Based on reactor geometry, agitator configuration, rotational speed, fluid rheology, and feed flow rates, VisiMix Chem analyzes key hydrodynamic parameters, including pressure distribution, velocity fields, circulation flow rates, and local turbulence characteristics. These characteristics include local energy dissipation rate (ε) and the smallest turbulent eddy size (δ), which directly influence macromixing and micromixing behavior within the reactor. Calculations are performed for real industrial reactors, where neither macromixing nor micromixing is ideal. The predicted reactor performance is then compared with that of an equivalent ideal reactor exhibiting perfect macromixing. This comparison allows users to quantify the influence of mixing limitations on chemical reaction performance, selectivity, yield, and by-product formation. During the development of VisiMix Chem, the hydrodynamic predictions generated by the software were extensively verified against corresponding simulations performed using VisiMix Turbulent. The verification demonstrated complete agreement between the two sets of hydrodynamic calculations, confirming the consistency and reliability of the VisiMix Chem simulation platform.
