Abstract:

The current situations, technical characteristics and key techniques of automatic aerodynamic optimization of compressors/fans, which are developing rapidly in recent years, are reviewed. It is concluded that the automatic design method is of high efficiency and suitable for the design of compressor and fan of high performance; and the parallel genetic algorithms should be considered first for reduction of the time consumed and the improvement of search efficiency. It is proposed that the further investigations should focus on blade parameterization method, acceleration method of flow field simulation and improvement of search efficiency.
