Adjoint-based Sensitivity Analysis for Multistage Turbomachinery

My PhD work was on the subject of adjoint methods for multi-stage turbomachinery CFD sensitivity analysis, where I further developed an existing adjoint solver of a proprietary CFD code for turbomachinery applications by implementing the adjoint counterpart of the mixing-plane interface, making use of automatic differentiation tools. This encompassed analyzing and implementing my routines on a complex piece of software while maintaining its parallelization via MPI. The adjoint solver was used to study the sensitivity of the performance of a stator-rotor stage of a low pressure turbine of a commercial jet engine to inlet and outlet boundary conditions and to the shape of the blades and hub geometry.
