Due to the manufacturing error and in-service degradation of gas turbines, there is always a
deviation between the actual geometry and the design geometry. This geometric deviation …

The adjoint method, among other sensitivity analysis methods, can fail in chaotic dynamical
systems. The result from these methods can be too large, often by orders of magnitude …

A discrete adjoint-based design methodology for unsteady turbulent flows on three-
dimensional dynamic overset unstructured grids is formulated, implemented, and verified …

Reduced order modeling plays an indispensible role for most real‐world complex models.
The objective of this manuscript is to hybridize local and global sensitivity analysis methods …

This paper analyses the adjoint solution of the Navier–Stokes equation. We focus on flow
across a circular cylinder at three Reynolds numbers,, a turbulent three-dimensional …

Sensitivity analysis methods are important tools for research and design with simulations.
Many important simulations exhibit chaotic dynamics, including scale-resolving turbulent …

Gradient-based sensitivity analysis has proven to be an enabling technology for many
applications, including design of aerospace vehicles. However, conventional sensitivity …

NASA'S X-43 hypersonic vehicle [1] holds the flight speed record among airbreathing
propulsion systems, having reached a self-sustained speed of Mach 10 for approximately 10 …

High-fidelity analysis tools can provide accurate predictions of the performance of a design.
However, these tools often have a higher computational cost when compared to lower …

In the framework of fusion energy research, divertor design and model calibration based on
plasma edge codes currently rely either on manual iterative tuning of parameters, or …
