Development of mixing models using electrical resistance tomography

Study of solid–liquid mixing in agitated tanks through electrical resistance tomography

“…Normally, the electrodes, located around the boundary of the vessel, make electrical contact with the fluid inside the vessels and are connected to the data acquisition system (DAS) by co-axial cables to reduce the electromagnetic noise and interference . The data acquisition system (DAS) is located in a portable unit and performs the various functions: signal measurement, demodulation, filtering, and control; waveform generation and synchronization; multiplexer control (share the current source and voltage measurement stages between any numbers of electrodes); and power supply (Mann et al, 1997a). Thus, it provides the quantitative data for conductivity distribution inside the vessel.…”

CFD simulation and ERT visualization of the displacement of yoghurt by water on industrial scale

“…For industrial use, ERT has been used to monitor the air core in cyclonic separators (Williams et al, 1995). ERT is also used as a tool to verify process simulations (Mann, Williams, Dyakowski, Dickin, & Edwards, 1997;Slater et al, 2002;Wood, Jones, Ganeshalingam, & Miles, 2004). For review of ERT applications in two-phase flow, see Dyakowski, Jeanmeure, and Jaworski (2000).…”

Introduction – an overview of process applications of tomographic techniques

“…In some cases, spatial effects could be recreated by developing a spatial network of interconnected models, such as in cellular mixing modelling (Mann, Williams, Dyakowski, Dickin, & Edwards, 1997). In this way, complex effects in a process reactor could be mapped with time, from which kinetic rates expressions and mixing could be derived, but without recourse to full computational fluids dynamics modelling.…”
