Abstract
This paper concerns on the computation and development of 2D turbine airfoil. In order to obtain a turbine blade shape with better performance, a physical programming based multidisciplinary optimization strategy is employed. The aim of multidisciplinary optimization here is to minimize the total pressure loss as well as to maintain a good structural stress. So there must be a compromise between aerodynamic performance and structural performance. That part of work is done by physical programming method in this paper, which can get more reasonable results than traditional ones. And the optimization process studied a range of design factors including the airfoil geometry parameters, the deviation angle, and a two-dimensional k-e turbulence model.
