Las and liquid flows in the tube under external transverse vibrations

Research output: Contribution to journalArticlepeer-review


Hydrodynamic parameters of gas and liquid flows in horizontal tube under external transverse vibrations and without them are studied experimentally. Test unit and investigation technique are described. Technique to calculate resistance coefficient under dispersion-circular flows at presence of vibrations is suggested. Pressure general drop within certain part is determined by friction losses which are linked with friction at channel wall, formation and acceleration of liquid drops wave formation and flowing-around of film wave surface by gas phase. Comparison of calculation results with experimental data has shown, that difference between them is maximum ± 25%.
