Adjoint Shape Optimization for Aerospace Applications

Speaker: Franklyn J. Kelecy, ANSYS, Inc.
April 8, 2021

Presentation

Abstract

Adjoint-based optimization methods have seen increased use in Computational Fluid Dynamics (CFD) simulations as a means of providing sensitivity information for flow solutions and as the basis of shape optimization techniques for performance improvement and robust design. This presentation will provide an overview of the Ansys Fluent adjoint solver and its application to selected aerospace cases. The topics covered will include:

Introduction to the adjoint method for CFD
>Advantages of adjoint methods for solution analysis and optimization
>A description of the adjoint solver workflow in Ansys Fluent, including the design tool and gradient-based optimizer
Some illustrated examples of the adjoint solver applied to a range of flow problems, including external aerodynamics, rotating machinery, heat transfer, and internal flow component design.

Seminar Participation

Attending In Person

For select seminars, you may wish to attend in-person if you are in the vicinity of NASA Ames Research Center. These AMS seminars are held in Building N258 in Room 127, just off the front lobby. Sessions available to attend in-person will be indicated in the announcement information. In-person participants without NASA badges will need a valid visitor badge (US citizenship or permanent residency is required) to enter the facility.
