Abstract
One of the main branches of engineering in the Republic of Tatarstan is the compressor industry. Produced compressors are used both in Tatarstan itself and throughout Russia. The need of the industry for a large range of centrifugal compressors leads to the need to reduce the time of their creation. In this regard, it is relevant to develop mathematical models that, having relative simplicity, accurately calculate real processes. These requirements are met by methods based on the use of a quasi-three-dimensional flow model in the flow parts of turbomachines. Two components of this method are now widely used. In this paper, we consider its third component, the so-called third two-dimensional problem. It is its solution that makes it possible to refine the shape of the flow surfaces that differ from axisymmetric ones and, thereby, more accurately model the spatial nature of the flow in the flow path.
