Experimental study of the amplitude-frequency characteristics in a two-channel system
Abstract
This paper is devoted to an experimental study of the amplitude-frequency characteristics in a two-channel system. In this study, we investigated the influence of the depth of the cylindrical resonator of the first channel on the amplitude-frequency characteristic of the flow at the inlet of the working part of the acoustic-convective dryer (ACD). The behavior of the amplitude-frequency characteristic of the working stream in the channel ACD with a consequent decrease in the specific depth of the cavity is considered. For a mathematical description of the behavior of the oscillation frequency as a function of cavity depth in devices based on the Hartmann principle, we use the classical Helmholtz equation for the natural frequency of a cylindrical cavity. The results of the calculations are in good agreement with the experimental data. Understanding the nature of the effects found in this study requires further research including a series of physical and computations experiments to investigate the flow dynamics in two-channel systems.
