Ship gas turbine compressor performance optimization method based on three-dimensional flow field analysis

The invention aims to provide a ship gas turbine compressor performance optimization method based on three-dimensional flow field analysis, and the method comprises the steps: taking a design working condition point as a reference, checking the flow field velocity distribution or Mach number distribution of different section heights from a first column of blades to a last column of blades, determining the flow matching condition of the flow field, and determining the flow matching condition of the flow field; pertinently judging the attack angle ranges of different section heights of each blade row, determining the blade inlet airflow angle and outlet airflow angle deviation, finely adjusting the blade inlet geometric angle and the blade outlet geometric angle, and completing optimization adjustment; for the separation of the end area, properly adopting the end bending technology in the modeling process of the stator blade, and optimizing the design. According to the method, the specific part where separation
