Special Issue Information
This Special Issue aims to cover ongoing advances in the development and application of adjoint methods in fluid dynamics. In addition to original research articles, review papers, letters or communications, technical reports, and extended versions of conference papers are likewise accepted.
The focus of this Special Issue is mainly, but not exclusively, on adjoint-based shape design, including properties of adjoint solutions, continuous, discrete and unsteady adjoint implementations, and multidisciplinary adjoint-based optimization of aircrafts, ships, and automobiles.
In addition to these topics, this Issue is open to any contribution concerning the application of adjoint methods to other computational fluid dynamics problems such as error estimation and goal-oriented mesh adaptation, stability analysis, etc.
We hope that this Special Issue can bring together all those working in adjoint methods within the CFD and fluid mechanics community.

Title: Adjoint-based Shape Optimization for Axisymmetric Aero-Engine Intakes

Abstract: A continuous adjoint-based aeroacoustic optimization software has been developed, based on a hybrid model including the Ffowcs Williams-Hawkings (FW-H) acoustic analogy, to account for the multidisciplinary design of axisymmetric intakes of aero-engines. This is applied to optimize such an intake, by parameterizing the generatrix of its lips using B-Splines; the target is to minimize the energy contained in the sound pressure spectrum, at the blade passing frequency at receivers located axisymmetrically around the axis of the engine. The engine is not included in the optimization and manifests its presence through available, independently computed, time-series of static pressure over the annular boundary of the simulation domain that corresponds to the inlet to the fan. The steady RANS equations are solved in the rotating frame of reference and post-processed to compute the flow quantities' time-series, required by the FW-H analogy. The numerical solution of the unsteady flow equations is thus avoided. The objective function gradient is computed using the continuous adjoint method, properly coupled with the analytical differentiation of the FW-H analogy. The adjoint equations are also solved in the rotating frame, by a steady solver.
