DEPENDENCE OF CHARACTERISTICS OF DETONATION WAVES IN MULTICOMPONENT BUBBLE LIQUID ON INITIAL PRESSURE

Relevance. Bubble liquids are a common working environment in a number of branches of the national economy. One of the most interesting processes is the propagation of detonation waves in a bubble liquid with a flammable gas inside the bubbles. Detonation waves can also propagate in a liquid with bubbles, partly consisting of inert gas. In this case, the presence of bubbles with inert gas is a certain control parameter for characteristics (amplitude, extent, propagation limits) of the detonation wave. In addition, there are experimental data on the influence of the initial pressure on the characteristics of bubble detonation waves in a multicomponent bubble liquid. This necessitates the investigation of detonation waves in multicomponent bubble systems for different values of the initial pressure. The aim of the research is to study the dynamics of detonation waves in a bubble liquid, partially consisting of bubbles with inactive (non-flammable) gas at different initial pressures. The object of research is detonation waves in a bubble liquid containing bubbles with an explosive (active) and non-flammable (inactive) gas. The research method is based on the fundamental equations of the mechanics of multiphase media, which are solved numerically. The results of investigations on revealing the features of the propagation of detonation waves in a multicomponent bubble liquid at various initial pressures allowed us to draw conclusions and give recommendations. As the initial pressure of multicomponent bubble media decreases, the velocity of propagation of detonation waves decreases. The dependence of the detonation wave velocity in a multicomponent bubble liquid on the initial pressure is close to linear.
