Abstract

This article is devoted to the study of the oblique fall of an acoustic wave from a pure gas to the boundary of a multifraction gas suspension with polydisperse inclusions of different sizes and materials. A mathematical model that allows to determine the reflection coefficient when an acoustic wave falls obliquely on the interface between two media is presented. Dependencies of the reflection coefficient on the disturbance frequency were calculated. Influence of the oblique angle of acoustic wave on the dependence of the reflection coefficient was established.

含多分散夹杂物的多重分馏气体悬浮液边界上的声波斜降

摘要

本文致力于研究声波从纯净气体到具有不同尺寸和材料的多分散夹杂物的多馏分气体悬浮液边界的倾斜下降。提出了一个数学模型，该模型可以确定当声波倾斜落在两种介质之间的界面上时的反射系数。计算反射系数对干扰频率的依赖性。建立了声波斜角对反射系数依赖性的影响。
