INVERSE DESIGN OF SHAPE IN INTERNAL AND EXTERNAL FLOWS USING PERMEABLE WALL CONCEPT

The permeable wall concept is used in an iterative shape design algorithm, in which a user-specified target pres­sure drives an initial guess to the final desirable shape. An euler flow model is used as the governing equation and internal and external flow examples are both pre­sented. The solution domain is discretized using the algebraic TFI method and Roeʹs scheme is employed for discrete flux calculations. Computational results show that the proposed iterative algorithm is robust and reli­able and converges quickly compared to commonly used shape design methods.
