Modeling the outflow of thick sediments from buffer tanks and discharge pipelines

Abstract

The paper deals with the problems linked to creating simple and reliable engineering methods for calculating bunkers both for the accumulation and discharge of thick precipitation and to the intensification of unloading and transportation of thick sediments. This problem is important both for obtaining a quality product in the production of powdered materials and suspensions and for achieving the required productivity. Current methods of calculation do not have sufficient generality and do not allow us to describe the regularities of the complicated process of the outflow of viscous suspensions with different theologies from buffer tanks and discharge pipelines of various configurations. Unlike the currently used methods, in this paper the formula for calculating the outflow rate from buffer tanks with accounting to the energy dissipation has been submitted. Such an approach allows us to propose a calculation scheme that can be adapted to different rheological models. The second important result is devoted to mathematical modeling the pneumatic-pulsed regimes of the overload of loosed materials. The mathematical model allowing for defining the resonance modes of thick sediments intensive overload and transportation has been submitted.The paper deals with the problems linked to creating simple and reliable engineering methods for calculating bunkers both for the accumulation and discharge of thick precipitation and to the intensification of unloading and transportation of thick sediments.
