Abstract

An embodiment of the present invention provides a method for controlling the flow loss of a blade boundary layer fluid, which includes the following steps: S1. classifying the movement of the blade boundary layer fluid; S2. according to the type of movement of the boundary layer fluid, obtaining Factors affecting the flow loss of the boundary layer fluid; S3. According to the factors affecting the flow loss of the boundary layer fluid, take corresponding measures to reduce the flow loss. The invention classifies the movement of the boundary layer fluid and adopts different control methods for different types of boundary layer movement, which has good versatility, strong practicability and obvious control effect.

Description

technical field [0001] The invention relates to the field of turbomachinery, in particular to a method for controlling the flow loss of a blade boundary layer fluid. Background technique [0002] Turbomachinery is widely used in industrial fields, such as aeroengines, ground gas turbines, steam turbines, mine ventilation and pipeline transportation, etc. Reducing the internal flow loss of the blades plays an important role in reducing energy loss and improving the work efficiency of the impeller. However, in the current process of reducing flow loss, it is often necessary to adopt different control methods according to different flow field conditions, and there is a lack of a general guiding method for quickly reducing flow loss. Contents of the invention [0003] In order to overcome at least one aspect of the above-mentioned problems, an embodiment of the present invention provides a method for controlling flow loss of fluid in a blade boundary layer, which has good vers...
