A derivative-free optimization algorithm for the efficient minimization of functions obtained via statistical averaging
Pooriya Beyhaghi, Ryan Alimo, Thomas Bewley
This paper considers the efficient minimization of the infinite time average of a stationary ergodic process in the space of a handful of design parameters which affect it. Problem…

Uncertainty Quantification of the time averaging of a Statistics Computed from Numerical Simulation of Turbulent Flow
Pooriya Beyhaghi, Shahrouz Alimohammadi, Thomas Bewley
Rigorous assessment of the uncertainty is crucial to the utility of numerical simulation of Turbulent flow. The Turbulent flows are often stationary and ergodic, after some initial…
