The Office of Research and Engagement will virtually host Gregg Abate, program officer for unsteady aerodynamics and turbulent flows at the Air Force Office of Scientific Research (AFOSR). AFOSR funds basic research at universities in various physical, information, and engineering sciences. Abate will give a presentation about working with AFOSR generally as well as the goals and interests of his research program in particular.
Date: October 20, 2020
Time: 1–2 p.m.
Registration required: Yes
Participants are required to register no later than October 16, 2020. An email with a link to the virtual presentation and password will be sent to all registered attendees prior to the workshop.
Program Description
The Unsteady Aerodynamics and Turbulent Flows portfolio supports basic research into the dynamics and control of aerodynamic shear flows including the interactions of these flows with rigid and flexible surfaces in motion. The portfolio is interested in aerodynamic flows arising in both internal and external configurations and extending over a wide range of Reynolds numbers. The portfolio emphasizes the characterization, modeling, prediction, and control of flow instabilities, turbulent flows, and aerodynamic interactions. A focus on the understanding of the fundamental flow physics is motivated by an interest in developing physically-based predictive models and innovative control concepts for these flows.
Basic Research Objectives
Research in this portfolio is motivated, in part, by the fluid-structure interactions, by vortex and shear layer flows, by the aerodynamic performance of novel configurations, and by enduring questions on transitional and turbulent flows. The portfolio maintains an interest in the dynamic interaction between unsteady fluid motion, linear and nonlinear structural deformations, and aerodynamic control effectors for a wide range of flight regimes.
The portfolio seeks to advance fundamental understanding of complex, time- dependent flow interactions by integrating theoretical, numerical, and experimental approaches: studies integrating these elements to improve understanding are strongly encouraged. Flow control studies are expected to involve an approach based on a fundamental insight into the flow dynamics. In cases where that insight may not exist, studies examining fundamental flow physics with a path to enabling control of the flow may be of interest. Flow control efforts integrating modeling, control theory, and advanced sensor and/or actuator technology for application to a flow of interest are encouraged. Note that basic research of the variety typically funded by the portfolio may not yet have a clear transition path to an application, but nevertheless should be relevant to US Air Force interests.
