description: Currently, methods of numerical modeling are widely used. They are especially widely used in the design of turbocompressors. For the specific task of designing new flowing parts of a centrifugal compressor, it is not recommended to deviate from the canonical design techniques, but it is preferable to supplement them with numerical methods. The present paper is devoted to the validation research of the blade diffuser in the intermediate stage of the centrifugal compressor using numerical modeling methods. Existing methods of numerical calculation of turbocompressors were investigated in the paper. A numerical research of the model was made, followed by validation of the results on a natural experiment. Optimization of the blade diffuser by seven parameters was made and stage calculations with different design of the blade diffuser were carried out. Recommendations were made on the use of the optimization algorithm. The theoretical results of the studies are important for the development of a multi-parameter optimization technique for blade diffusers of centrifugal compressors using numerical modeling methods.
