摘要

在工作中,根据离散模型和连续模型研究和确定了液体介质中空化气泡运动的声学参数。该研究基于这样一个假设,即声学处理工作过程的有效参数的确定是通过应用从离散到连续的技术环境处理类型的过渡物理模型来实现的。得到的解析依赖关系允许计算振荡的幅度和自然振荡的频率。借助规定的公式,可以确定不同频率的振荡振幅的放大或衰减区域。提出了确定自然振荡频率的公式,该公式考虑了介质性质从初始阶段的均匀到在规定的自然振荡频率下出现空化气泡的变化。给出了强度、压力、振荡幅度、速度、加速度、粘度和最大气泡半径的数值。所得数值可用于实际计算不同性质和工艺环境的声处理参数。

Research and determination of the acoustic parameters of the movement of a cavitation bubble in a liquid medium according to discrete and continuous models
In the work, the study and determination of the acoustic parameters of the movement of a cavitation bubble in a liquid medium according to discrete and continuous models was carried out. The research is based on the hypothesis that the determination of the effective parameters of the work process of acoustic processing is implemented by applying a transitional physical model from a discrete to a continuous type of processing of the technological environment. The obtained analytical dependences allow to calculate the amplitude of oscillations and the frequency of natural oscillations. With the help of the specified formulas, it is possible to determine the zones of amplification or attenuation of the amplitude of oscillations for different frequencies of oscillations. The proposed formula for determining the frequency of natural oscillations, which takes into account changes in the properties of the medium from homogeneous at the initial stage to the appearance of cavitation bubbles at the specified frequency of natural oscillations. Numerical values of intensity, pressure, amplitude of oscillations, velocity, acceleration, viscosity and maximum bubble radius are given. The obtained numerical values can be used in practical calculations of acoustic processing parameters of different nature and properties of technological environments.
