Description

technical field

[0001] The invention relates to the field of fan impellers, and more specifically relates to an ultra-high-speed, high-efficiency, complex-curved-surface centrifugal impeller. Background technique

[0002] Centrifugal impeller refers to the wind wheel that enters the air axially and exits radially, and uses centrifugal force (depending on the speed and outer diameter) to do work to increase the pressure of the air.

[0003] The performance of the centrifugal impeller directly determines the performance of the fan equipment. With the development of the turbine rotating machinery towards high speed, high efficiency and high reliability, the design requirements for the centrifugal impeller are getting higher and higher. At present, the design of the centrifugal impeller is mainly based on the three-dimensional flow design theory, and the computational fluid dynamics analysis of the flow channel has important engineering significance for the design of the medium ...
