Abstract
This paper presents an application of electrical resistance tomography to the investigation of mixing processes at plant scale. An 8-plane 1 6-electrode ring sensor installed within a stirred tank with a 1.5 m i nner diameter is described. Three-dimensional and nonstationary behavi our of mixing processes are illustrated by the images obtained simulta neously from eight axial levels along the tank height. The results ill ustrate air-core vortex detection, miscible fluid mixing and gas-liqui d mixing processes. (C) 1997 Elsevier Science Ltd. All rights reserved .
