Plug flow of yoghurt in piping as determined by cross-correlated dual-plane electrical resistance tomography

Henningsson, Marcus LU ; Östergren, Karin LU and Dejmek, Petr LU orcid (2006) In Journal of Food Engineering 76(2). p.163-168
Abstract
Cross-correlation of electrical resistance tomography (ERT) was used to determine the velocity profile of yoghurt in a pipe of industrial dimensions. In viscometry, at shear rates higher than 10 s(-1), the yoghurt followed the power law model with a K-value of 3.7 Pa s(n) and an n-value of 0.37. In pipe flow, however, within the tested mean velocity range of 0.05-0.25 m s(-1), the yoghurt appeared to flow as a plug. The local velocity was constant from the centreline to within 3 mm of the tube wall, which corresponds to the resolution of the ERT method. (c) 2005 Elsevier Ltd. All rights reserved.
