Sensitivity analysis is considered a fundamental tool in aerospace engineering, allowing to evaluate the impact of parameters variations and optimize the aerodynamic and struc- tural design. There has been much effort on the development of both theoretical and numerical frameworks for sensitivity calculations through adjoint solutions. This work explores the application of the continuous adjoint method to optimize the geometry of a pipe through which turbulent fluid circulates, with a specific focus on leveraging the Spalart-Allmaras turbulence model for accurate representation of turbulent effects, to reduce the pressure drop. The synergy between the adjoint method and turbulence modeling becomes evident, with implications for advancing the design and optimization of engineering devices in various industries
