A reliable and efficient aerodynamic design optimization tool using evolutionary algorithm has been developed for transonic compressor blades. A real-coded adaptive-range genetic algorithm is used to improve efficiency and robustness in design optimization. To represent flow fields accurately and produce reliable designs, three-dimensional Navier-Stokes(More)
A method is presented that computes the conjugate heat transfer problem using a hybrid overset grid system. The hybrid grids for the ¯ uid and solid structure regions use Chimera overset structured grids and unstructured grids, respectively. The numerical analyses require the ¯ ow® eld solution and material thermal response to be obtained simultaneously. A(More)
We propose a novel approach of three-dimensional hybrid grid methodology, the DRAGON grid method in the three-dimensional space. The DRAGON grid is created by means of a Direct Replacement of Arbitrary Grid Overlapping by Nonstructured grid, and is structured-grid dominated with unstructured grids in small regions. The DRAGON grid scheme is an adaptation to(More)
