RESOLVENT-BASED ESTIMATION FOR CONTROL OF TURBULENT AERODYNAMIC FLOWS
Abstract
We will develop an improved method by leveraging the existence of organized motions within the flow called coherent structures. These coherent structures exhibit correlation over long time- and length-scales, and thus provide a principled, physics-based means to estimate the state of a flow at one location using measurements taken at another location. Motivated by this insight, we will develop an optimal estimation method using state-of-the-art models for coherent structures and apply it to flows relevant to aerodynamic applications, including the flow around on airfoil. The final outcome of this project will be a new flow estimation framework, validated and optimized to predict aerodynamic flow behavior from limited, physically realizable measurements. This capability would help the Air Force maintain its technological superiority by enabling aerodynamic performance enhancements such as increased maneuverability, reduced drag, and improved safety.
