The influence of 3g and 4g vibration on the disperse structure of low-frequency and medium-frequency oscillation

Abstract

The paper is devoted to experiments carried out on the DEVS– 200 A – 1 stationary testing bench that resulted in changes of hydrodynamic processes in the disperse structure under the influence of lateral vibration. The influence of vibration parameters (frequency of vibration and vibration accelerations) changes the structural model of two-phase flows. A classical two-phase structure wherein the whole surface of the elastic tube is caught in the field of lateral vibration is in its initial state prior to a certain threshold of vibration acceleration. The work is not concerned with the problems of structural changes. Two-dimensional graphs show the dependence of hydraulic parameters in the field of vibration influences. Three-dimensional spatial models characterize interdependence between three hydraulic parameters acted upon by vibration processes. Four schedules and two nomograms characterizing the obviousness of hydrodynamic dependences on the influences of vibration on them are presented.
