Main properties of a gas-liquid mixture in pipes

Recently carried out experimental and theoretical studies with gas-containing liquids have shown that rheological and relaxation properties of gas-liquid systems under pre-transition conditions (i.e., in pressures exceeding the saturation pressure, but close to it) are largely determined by the presence of “micro germs” –the smallest gas bubbles, the cooperative action of which manifests itself when approaching the saturation pressure [1]. When solving many practical problems, it becomes necessary to study the wave propagation with regard to the influence of the interaction between the liquid and the wall of the deformable pipe. In this case, the system consisting of a deformed body, liquid, and gas is obtained; therefore, the study should be carried out with regard to the interaction forces between the deformed body, liquid and gas.
