...Guang Xi; Yong Zhang; Cheng Ji; Chenqing Zhang In recent years, we have made several improvements to the geometric parameterization method, the surrogate model method, and the sampling method, with the goal of making the traditional surrogate model-based optimization method applicable...

...Cheng Ji; Zhiheng Wang; Guang Xi In recent years, in order to achieve higher performance, the number of design variables used in the aerodynamic optimization of turbomachinery (based on surrogate models) has increased significantly. However, the increase in the design dimensions brings the problems...

..., which can lead to significant variations in their performance and stability. In this study, design guidelines for robust design against manufacturing deviations of HGJB supported micro-turbocompressors are proposed. These guidelines are based on surrogate model-assisted multi-objective optimization...
