Abstract

It is highly desirable to be able to interrogate in 3-D the whole fluid inside a typical stirred vessel, especially when used as a chemical reactor. Electrical resistance tomography (ERT) 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 2.3m3 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 colour, giving a 5-D 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 visualise in 5-D the way solid resides on the vessel base behind baffles as well as indicate the height to which solids are effectively suspended. The dynamics of mixing after a charge of solids can also be captured and visualised using augmented-reality. The facility to envisage mixing information in up to 5-D offers new possibilities for control action linked to spatial distributions of phases and components.
