This paper investigates the problem of filling a spherical cavity in a liquid and the effects of impurities on cavitation behavior. The results show that for all models, the cavity filling time is finite if the surface tension is not zero. However, the relaxation factor can significantly alter the flow pattern by slowing down the filling process and reducing the energy accumulation during bubble collapse.
The problem of filling a spherical cavity in a liquid has attracted the attention of many authors. The study of bubble behavior in liquid allows to estimate the consequences of cavitation processes, which can lead to the intensive destruction of the material surface. Regarding this connection, it becomes necessary to study the influence of impurities, including polymeric additives on the strengthening or suppression of cavitation. In this paper, this problem is considered in three models of a relaxing fluid. It is shown that for all models, the cavity filling time is finite if the surface tension is not equal to zero. This result was previously established for the cases of ideal and viscous fluids. However, the relaxation factor can significantly change the flow pattern by slowing down the filling process and lowering the level of energy accumulation during the bubble collapse.
