AI Technical Summary
Existing technologies make it difficult to effectively optimize the design while keeping the compressor flow path shape unchanged, which limits the improvement of compressor performance.
By selecting discrete points in the compressor flow path, calculating the first radial coordinate difference, and changing the size of the discrete points within a certain range to form a second radial coordinate difference while maintaining the same positive and negative attributes, and combining spline fitting and genetic algorithm to optimize the flow path curve, one-dimensional calculation is performed to obtain the optimized design scheme.
It enables a shorter design cycle, rapid identification of optimized parameter range, and a better compressor flow path design scheme while maintaining consistent flow path direction, providing reliable reference values for subsequent designs.
