Abstract
Features of the flw modes of viscous incompressible flid in the cavity between the two rotating cones make a big difference due to the importance of the problem of analyzing the characteristics of the kinetics of these streams for centrifugal separating equipment in the dairy, meat, microbiological and other related industries. It is obvious that to study the kinetic patterns of flid movement in a narrow gap between the two neighboring truncated cones it is necessary to have a correct apparatus of mathematical modeling of the current in this gap, bearing in mind that the flw induced by a linear source on the rotor rotation axis approximates the flw of the loosely concentrated system «liquid + solid» in the slit cavity between the separator plates. The aim in this paper: based on the laws of maintaining the pulse and mass of the liquid to obtain an asymptomatically accurate solution to the problem for the analyzed flw; on the basis of the received solution, in a criminal form, to investigate the dependence of kinetic characteristics of the flw from the current criteria; to justify the adequacy of the results of the calculation to the regime parameters of the operating equipment. In the implementation of the solution of the problem of the kinetics of a liquid flw, constructed in the form of a parametrically dependent on the criterial parameters of the functional series, an algorithm for determining the members of the constructed series is proposed in the form of an iterative procedure. On the basis of this algorithm, a numerical study was carried out with a meaningful analysis of the velocity and pressure fild of the flw under consideration according to the values of the criterion parameters characteristic of industrial separation equipment.
