Features of the Reflection of Pulse Signals from a Layer with Vapor-Gas Bubbles in Front of a Rigid Wall in Water

Abstract

The paper presents the results of a study of the evolution of a wave signal when reflected from a rigid wall with a vapor-gas bubble “curtain” located in front of it in a liquid, which takes into account the heat and mass transfer on the interphase surface in the acoustic approximation. Based on the numerical calculations, using the fast Fourier transform method, wave patterns for the evolution of pressure pulses are obtained and the influence of various parameters of the state of a liquid with vapor-gas bubbles on the reflection and passage of acoustic waves through the curtain in front of the solid wall is analyzed.

期刊介绍： High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
