The simulation of the process of leakage of finely dispersed bulk material from the conical bunker of the hopper during vibrational perturbation of the flow by a conical bottom on the basis of the Lorentz model, which allows describing the behavior of the bulk product under the action of vibration, is considered. Since the fine-dispersive SM under the influence of mechanical vibrations behaves in a similar way to the liquid, the most effective way of obtaining the Lorentz model was to deduce it from the Navier-Stokes equations. The dynamics of leakage of SM, the influence of the parameters of the well and vibration modes on the efficiency of the leakage process have been analyzed.


Keywords: unloading well, loose material, vibrational bottom, leakage, parameters of the well, modes of oscillations

History of journal:

In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published  94 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Kaletnik H.M  PhD , professor, academician NAAS is the chief editor of the "Vibrations in engineering  and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
