THE MATHEMATICAL MODEL OF FEED SUSPENSION MOVEMENT IN THE CHANNELS OF ROTARY IMPULSE DEVICE

Abstract

The article is devoted to theoretical and experimental studies of the use of rotary impulse devices for the prepa-ration of liquid feeds by the dispersion method. On the basis of the non-stationary Bernoulli equation, a mathematical model of the motion of the feed suspension in the channels of the rotary impulse apparatus is proposed; it takes into account the effect of the feed particles on the hydraulic resistance of the transition between the channels of the rotor and the stator. An algorithm is proposed for approximate calculation of coefficient values, which takes into account the degree of blocking of the cross-section between the channels of particles of the material being processed. The method of numerical solution of the non-stationary Bernoulli equation with the use of computer algebra systems is substantiated. This method makes it possible to determine the hydrodynamic parameters of the feed suspension and the delivery of a rotary impulse apparatus. Experimental research of productivity of the rotary impulse device during the processing of the feed suspension is carried out. A statistical evaluation indicates the correspondence between the theoretical and experimentally obtained results.
