Multi-objective aerodynamic optimization design of multi-element airfoil using kriging model
semanticscholar(2012)
Abstract
The Kriging-based multi-objective optimization design method for multi-element airfoil is developed in this paper. by introducing the Navier-Stocks solver with S-A turbulence model, the zonal patched grids and the genetic algorithm, the lift coefficient under the landing condition is maximized with the moment coefficient as the constraints. In order to reduce the computational time and cost, Kriging model is applied to the process of the optimization design. EI method is introduced to give additional sample points for improving the accuracy of the model. A single and multiobjective optimization design for the position of multi-element airfoil is carried out. Results show that this method can be an attractive design tool for multi-element airfoil.
