Shock waves in a liquid containing small gas bubbles

摘要: Numerical and experimental studies of the transient shock wave phenomena in a liquid containing non‐condensable gas bubbles are presented. In numerical analysis, individual tracked to estimate effect volume oscillations on phenomena. Thermal processes inside each bubble, which have significant influence oscillation, calculated directly using full equations for mass, momentum energy conservation, those results combined with averaged conservation bubbly mixture simulate propagation wave. A silicone oil/nitrogen bubble mixture, initial radius is about 0.6 mm fraction 0.15% – 0.4%, used tube experiments. The inner diameter chosen be 18 52 order investigate multidimensional effects fairly uniform agree well ones computed spatial distribution bubbles. On other hand, all experiments, tubes not distributed uniformly, being relatively concentrated along axis tube. This non‐uniformity substantially alters profile waves. predictions where such taken into account data.
