Popis: | Experiments on evaluation of the effect of bubbles on the hydrodynamic structure of two-phase bubbly downflow were carried out by means of PIV / PLIF method. Experiments were performed at Re = 5000 and gas flow rate ratio β = 1%. Data were obtained on the distribution of liquid velocity and its fluctuations, as well as on the mean bubble diameter. The results were processed using a computer bubble detection algorithm. To validate the received data, they were compared with the results obtained in [1] for the same pipe using electrochemical method. A good agreement was found for R. M. S. of liquid velocity distribution for different methods. |
