Abstract

The invention provides an optimal design method and system for blades of an axial flow compressor, and the method comprises the steps: converting a partial differential equation describing a flow process into an ordinary differential equation according to the flow characteristics of the axial flow compressor; establishing a state equation of the axial flow compressor; determining optimal diffusionfactor distribution of the axial flow compressor based on the state equation according to a preset constraint condition; and taking the outlet angle as a control variable, and performing iterative operation according to parameters corresponding to the geometric modeling of the three-dimensional space of the blade and the ordinary differential equation to obtain the blade profile meeting the optimal diffusion factor distribution of the axial flow compressor. The axial flow compressor blade designed by adopting the method has the characteristics of high efficiency and large stall margin, and issuitable for various design working conditions and variable working conditions.

Description

technical field [0001] The invention relates to the technical field of fluid machinery, in particular to an optimization design method and system for blades of an axial flow compressor. Background technique [0002] Axial flow compressor is the most critical rotating machinery in important industries such as large-scale power generation and military industry. Its work efficiency, reliability and safety have always been the focus of attention of academic circles and business circles. The high efficiency (including design working conditions and variable working conditions) and reliability (long-period trouble-free operation) of the unit play a very important role in the economic benefits of the enterprise. In the blade design of this type of machinery, it is not only necessary to have a high efficiency of a single design condition, but also to have a comprehensive advanced design that can meet multiple design conditions, efficient performance under variable conditions, and a l...
