To efficiently calculate the sensitivity derivative of hydrodynamic objective functionals with respect to the shape, the adjoint Navier-Stokes equations were derived analytically. Consistent adjoint discretisation schemes were developed term-wise from the primal finite-volume discretisation. The adjoint method, implemented in the framework of a general-purpose pressure-correction based RANS code for unstructured grids, was validated against analytical solutions and verified by means of the direct-differentiation method. The adjoint-based sensitivity derivative was computed to guide a manual re-design of a ship hull to improve the wake field. Moreover, automatic shape-optimisation runs were carried out to reduce the power loss for ducted flows.
