Tomographic imaging of industrial process equipment: techniques and applications

Polymer flocculation of calcite: Experimental results from turbulent pipe flow

“…Flocculant/suspension macroscale mixing is likely to be highly scale dependent, and its importance is evidenced by the industrial practice of using a very dilute flocculant stream (0.01–0.1%21, 30) and various proprietary feedwell designs to produce efficient mixing. It is difficult to replicate industrial‐scale mixing conditions on a laboratory‐scale, however, the use of emerging techniques like computational fluid dynam‐ ics,75, 76, 77 or electrical impedance tomography13, 78, 79, 80, 81 are likely to increase the understanding in this area.…”

Fabrication of Ambipolar Organic Heterojunction Transistors with Various Sexithiophene Alkyl-Substituted Derivatives

“…The simplest implementation of the transformation described above is linear back projection (LBP), which was originally developed for hard-field techniques. Variants of LBP have now also been employed in a number of softfield applications [18][19][20]. For example, in ECT,Q is generated by calculating the perturbation to the background capacitance measurements resulting from each pixel in turn being occupied by the target material (such as oil or water) [21].…”

Tomographic Techniques for Characterising Particulate Processes

“…This can be achieved by cross-correlating signals from two sets of capacitance imaging sensors mounted axially along the pipeline [86]. (iii) Resistance imaging has been used to measure miscible 1iquidAiquid and solid/liquid concentration profiles and phase boundaries in mixing and separation operations [71,74,[87][88][89][90]. The spatial resolution is comparable to the capacitance methods described above.…”
