2 Measuring the Cavitation Cloud by Electrical Impedance Tomography

Authors: Jiří Primas, Michal Malík, Darina Jašíková, Václav Kopecký, Michal Kotek

Abstract:

This paper is a case study dealing with the viability of using Electrical Impedance Tomography for measuring cavitation clouds in a pipe setup. The authors used a simple passive cavitation generator to cause a cavitation cloud, which was then recorded for multiple flow rates using electrodes in two measuring planes. The paper presents the results of the experiment, showing the used industrial grade tomography system ITS p2+ is able to measure the cavitation cloud and may be particularly useful for identifying the inception of cavitation in setups where other measuring tools may not be viable.

1 Measuring of the Volume Ratio of Two Immiscible Liquids Using Electrical Impedance Tomography

Authors: Jiří Primas, Michal Malík, Darina Jašíková, Václav Kopecký, Michal Kotek

Abstract:

Authors of this paper discuss the measuring of volume ratio of two immiscible liquids in the homogenous mixture using the industrial Electrical Impedance Tomography (EIT) system ITS p2+. In the first part of the paper, the principle of EIT and the basic theory of conductivity of mixture of two components are stated. In the next part, the experiment with water and olive oil mixed with Rushton turbine is described, and the measured results are used to verify the theory. In the conclusion, the results are discussed in detail, and the accuracy of the measuring method and its advantages are also mentioned.
