Design basis development for centrifugal turbo machines with a coaxial impellers location for mining-and-metallurgical industry conditions

Abstract

The article considers the main ways to improve the modern designs of centrifugal turbo machines. The existing methods of their design are analyzed. One of the development options is considered which consists in using the coaxial impellers location in centrifugal turbo machines. A technique for designing a coaxially mounted impeller is presented.
