Paper Abstract

It is highly desirable to be able to interrogate in three dimensions the whole fluid inside a typical stirred vessel, especially when used as a chemical reactor. Electrical resistance tomography can scan the fluid with a spatial discrimination of the order of O(103) voxels with video frame rate acquisition speeds. Some new augmented-reality results are presented for a 2.3 m3 pilot scale vessel detecting miscible fluid mixing of a brine tracer pulse and solid– liquid mixing. The images are created by solid-body iso surfaces between which are variable opacity layers. Extra augmentation can be achieved by the use of color, giving a five-dimensional (5D) representation of the mixing process. For miscible mixing, the geometry and spatial patterns clearly highlight the effect of injection position on mixing rates. For the solid–fluid mixing, it is possible to visualize in 5D the way solid resides on the vessel base behind baffles as well as indicate the height to which solids are effectively suspended. The results have also been represented as conventional axial solids distribution profiles. The dynamics of mixing after a charge of solids can also be captured and visualized using augmented reality. The facility to envisage mixing information in up to 5D offers new possibilities for control action linked to spatial distributions of phases and components.
