dc.description.abstractA new design approach for a delicate treatment of complex geometries such as a wing / body configuration is arranged using overset mesh technique under large scale computing environment for turbulent viscous flow. A new design approach for a delicate treatment of complex geometries such as a wing/body configuration is arranged using overset mesh technique under large scale computing environment for turbulent viscous flow. Various pre-and post-processing techniques which are required of overset flow analysis and sensitivity analysis codes are discussed for design optimization problems based on gradient based optimization method (GBOM). Various pre- and post-processing techniques which are required of overset flow analysis and sensitivity analysis codes are discussed for design optimization problems based on gradient based optimization method (GBOM). The overset flow analysis code is validated by comparing with the experimental data of a wing / body configuration (DLR-F4) from the 1st Drag Prediction Workshop (DPW-Ⅰ). The overset flow analysis code is validated by comparing with the experimental data of a wing/body configuration (DLR-F4) from the 1st Drag Prediction Workshop (DPW-Ⅰ). In order to examine the applicability of the present design tools, careful design works for the drag minimization problem of a wing / body configuration are carried out by using the developed aerodynamic shape optimization tools for the viscous flow over multiple-body aircraft geometries.
