Abstract:
The interaction of a step-like pressure wave with a spherical gas-liquid cluster in a cylindrical channel filled with a liquid has been studied numerically. It has been shown that the cluster generates a solitary pressure wave of large amplitude. The influence of a bubble cluster on the dynamics of multiple reflection of a pressure wave from the boundaries of the cylindrical channel has been investigated. The results of numerical calculations are in good agreement with experimental data.
The work was carried out within the framework of the state task of the Ministry of Education and Science of the Russian Federation in the field of scientific activity “Solving Urgent Problems and Studying Processes in Petrochemical Industries Accompanied by Flows of Multiphase Media” (No. FEUR-2020-0004).
