The unsteady continuous adjoint method for minimizing flow-induced sound radiation [PDF]
This paper develops the unsteady continuous adjoint method for aeroacoustic problems governed by time-dependent turbulent flows. To predict flow-induced sound radiation from a body in free-stream, an incompressible Improved Delayed Detached Eddy Simulation is firstly performed.

A multiphase CMAQ version 5.0 adjoint [PDF]
We present the development of a multiphase adjoint for the Community Multiscale Air Quality (CMAQ) model, a widely used chemical transport model. The adjoint model provides location- and time-specific gradients that can be used in various applications ...

Continuous Adjoint Method for Unstructured Grids [PDF]
Adjoint-based shape optimization methods have proven to be computationally efficient for aerodynamic problems. The majority of the studies on adjoint methods have used structured grids to discretize the computational domain. Because of the potential advantages of unstructured grids for complex configurations, in this study we have developed and ...
