Immersed Boundary Based Computational Fluid Dynamics Applied to Aerodynamic Design Optimization

In aerodynamic shape optimization using meta-heuristics such as evolutionary algorithms, the body-fitted mesh method based computer fluid dynamics is often employed. However, it has difficulty in efficiency and accuracy, can undermine advantages of global methods. The generation also decides success or failure individual evaluation. this study, we developed a for on computational that robustly calculate arbitrary-shaped flowfields Cartesian with immersed boundary instead mesh. was examined by solving two airfoil design problem.
