Numerical modeling of reactor clarifier characteristics, taking into account the nonstationary motion of the loading particles

[摘要] The physical model of the contact mass' particles interaction and the process of filtration in a fluidized layer is investigated in the article. Differential equations, describing the occurrence of non-stationary pulsations in the reactor-filtering component are given here. The computational experiments made it possible to determine the main kinematic dependencies and the way of contact mass' parameters influencing on them. An estimate of the nonstationary process parameters, such as a period and frequency of oscillations, was obtained, and the estimated energy losses due to the occurrence of self-oscillations were calculated.
