“…The relative difference between the experimental and the calculated data was, in general, smaller for low quality flows. The Abdul-Razzak et al [4] and Huang et al [6] correlations for flow quality are not of as general application as Chisholm's [3], which suggests they are more adequate for use with the original fluids tested.…”

“…Therefore, a single phase flowmeter is not capable of measuring the flowrate and phase fraction simultaneously and a combination with other measuring devices is necessary. A lot of combined methods have been developed to measure the two-phase flowrate and phase fraction (Huang et al ,2005;Geng et al ,2007;Meng et al ,2010;Meribout et al ,2010;Oliveira et al ,2009;Reis and Jr ,2008;Sun ,2010;Zhang et al ,2010;Zheng et al ,2008).…”

“…There are many intrusive as well as non-intrusive methods, which are commonly used to measure void fraction in multiphase flows. Some of the most popular are the method of gamma rays absorption (Stahl and von Rohr [9]), the method of magnetic resonance (Daidzic et al, [1]), tomography and impedance methods (Dong et al, [2]; Jaworek et al, [6]; Huang et al, [5]), double sensor probes (Hogsett and Ishii, [4]; Hibiki and Ishii, [3]) or isokinetic (suction) methods (Mayr and Arch, [7]). …”

The Pelton turbines are the part of the pump-storage scheme that is working under permanent backpressure conditions. The knowledge of air-absorbing and degassing in the vessel which follows the turbine chamber is important for the safe and economical working of the turbine. In the case of so called hydraulic short circuit the influence of air bubbles for the safe operation of turbines and pumps is very important. To estimate the volume void fraction in two-phase flow, the measurement method was developed, which is based on the computeraided visualization. Acquisition of flow images by a fast video camera followed by the computer processing of the acquired images enables the determination of the void fraction via the average value of grey level intensity of the acquired flow images. A relationship between the void fracture and the average grey level intensity was obtained through calibration of the measurement system. Simultaneous measurements with the other measurement method revealed suitability and applicability of the visualization method in a real industrial environment such as a tailwater channel of a Pelton turbine. Apart from that, a study revealed that by further processing the images a number of other important information on the flow, such as bubble size and shape, average bubble direction and velocity, can be obtained by the described method.
