| Abstract: | Geometric genetic algorithm is very suitable to solve the shape optimization problem with close contour, i.e., optimization of airfoil profile, for its particular chromosome representation of variables to be optimized and its easiness in coding and decoding process. In this paper, the geometric genetic algorithm is applied to improving the design for blade profile of a centrifugal diffuser cascade in fluid-machines. Numerical simulation shows that this algorithm is satisfactory. |
