... as follows: 4 f 1 - f 2 f 1 - f 3 = 0 . 82 f 3 , for instance, horizontal side arm slug frequency, based on the experimental data obtained for frequency measurements in horizontal pipe for different pipe size diameters according to Azzi et al...

... by means of ring impedance probes. From dynamic void fraction measurements the mean void fraction values, the probability distributions of void, the liquid film height in the gas cavities and the slug frequencies have been evaluated. The analysis of the results showed that the flow structure deeply...
