Abstract
This chapter deals with the investigation of potentials in energy efficiency optimization for widespread agitated vessels. A lab-scale model is derived from an industrially used reactor vessel with immersed helical coils, which is utilized for several chemical basis operations. The model is analyzed with particle image velocimetry (PIV) and laser-induced fluorescence (LIF) concerning velocity and concentration fields, which gives a good validation basis for CFD analysis. However, it is challenging to validate simulations of industrial reactors. In this work, the idea is pursued of comparing the flow fields of simulations and measurements in order to validate the computational results. The simulation task implies the generation of complex geometry meshes, solving for steady-state, as well as for transient solutions, and seeking fast and effective methods. An approach to the validation of technical, large-scale simulation results is proposed through comparison of mixing times in simulations and industrial trial runs.
