The Application of EIS and PIV Methods to the Measurement of Aerated Flow

Abstract

The paper describes measurements in the aerated water medium using modern methods PIV (Particle Image Velocimetry) and EIS (Electrical Impedance Spectrometry), which are applied in the Laboratory of Water Management Research (LVV) of the Department of Water Structures (UVST) at the Faculty of Civil Engineering (FAST) of Brno University of Technology (VUT). Measurements of the water medium were carried out for three different aeration intensities at special experimental workplaces. The experiment was focused on the capability of the methods to monitor the air content in the water.
