This article focuses on improving the feeding section of the cotton machine cleaner. In existing feeders, in a certain period of time, raw cotton is not loosened enough, which in turn leads to a decrease in the cleaning effect of the machine. In this regard, in order to eliminate this drawback, a theoretical task was set to study the reduction of cotton to a dispersed state by supplying an air flow to the feed zone and achieving a uniform cotton supply to the cleaning machine. To solve the problem, the methods of the theory of ideal fluid flows with the use of the theory of functions of a complex variable are used. The problem is solved in parametric form, while solving Zhukovsky functions and Schwarz integral formulas are also used. To determine the geometric and mechanical characteristics of the flow, the corresponding equations are obtained. The article also discusses some special cases of the problem. All possible options for solving the problem of the movement of two mixtures of raw cotton and air, as well as the necessary design parameters, have been obtained. The results obtained make it possible to determine the geometric dimensions in the design of the feeders.
