S-tipi hava alığı eniyilemesi için ayrık adjoint tabanlı çözücü geliştirilmesi

A discrete adjoint-based aerodynamic shape optimization framework is developed to optimize an S-type intake. An implicit time-stepping scheme and iterative linear system solver are implemented into the in-house flow solver. The adjoint code for the selected objective functions is generated using automatic differentiation. The flow solver is validated flows through the RAE-M2129 S-type intake. Verification of the adjoint sensitivities is performed using the central finite difference method. In the shape optimization process, the boundary surface and the mesh are deformed with the Free-Form Deformation approach. Following the validation studies, the baseline RAE-M2129 S-type intake is successfully optimized for single and multi-objective functions based on the performance parameters; pressure recovery and distortion coefficient at the AIP.
