The Time-Domain Continuous Adjoint Method

2010
The adjoint method is a mathematical tool that allows us to compute the gradient of an objective functional with respect to the model parameters very efficiently. In this chapter we derive a general formulation of the adjoint method that is independent of a particular physical problem.

Unsteady Continuous Adjoint Approach for Aerodynamic Design on Dynamic Meshes

AIAA Journal, 2014
This paper presents the development and application of a new unsteady continuous adjoint formulation for optimal shape design of aerodynamic surfaces in motion, such as rotating or pitching applications. The arbitrary Lagrangian–Eulerian form of the unsteady, compressible Reynolds-averaged Navier–Stokes equations with a generic source term is ...

An Unsteady Aerodynamic/Aeroacoustic Optimization Framework Using Continuous Adjoint

2020
In this paper, an unsteady aerodynamic/aeroacoustic optimization framework is presented. This is based on the continuous adjoint method to a hybrid acoustic prediction tool, in which the near-field flow solution results from an unsteady CFD simulation while the acoustic propagation to far-field makes use of an acoustic analogy.
