NICOP - The Application of Dielectric Barrier Discharge Plasma Actuators on Active Flow Control around a Bluff Body
Abstract
The Application of Dielectric Barrier Discharge Plasma Actuators on Active Flow Control around a Bluff Body:Note to TD: I discussed this initiative with you in our email correspondences on 4 Feb 2016. The amount is reasonably low given the value and the research work to be done. Prof. Wen does great research work and is very well known in the field. He is very interested in working with researchers in U.S. NRE. His basic research effort will be very valuable to the work at NSWCCD supported by ONR. This effort is not only valuable basic research work, but also consistent with our China/HK S&T engagement strategy. With your approval (email attached in the document section), I went ahead and solicited the final proposal and submitted a DCP for OSD/P approval. a. Technical: The application of dielectric barrier discharge (DBD) plasma actuators on active flow control around a bluff body is proposed in this project. The specific objectives of this research effort include: (1) to optimize DBD (dielectric barrier discharge) plasma actuators and to investigate the dielectric property of materials to enhance the performance of DBD plasma actuators on a flat plate model; (2) to apply different DBD configurations using the optimized DBD plasma actuators on the semi~circle~square body to compare the control authority and their impacts on the flow structure; (3) to optimize the control strategy based on the underlying flow control mechanisms of DBD plasma actuators on the bluff body; and (4) to compare the experimental results with the numerical simulations by the ONR collaborator (Dr. Yu~Tai Lee at NSWCCD, Code 871). b. Relevance: The interest in technologies that broaden the roles and capabilities of unmanned aerial vehicles (UAVs)/micro aerial vehicles (MAVs) has increased rapidly over the last decade in ONR, the US Naval Research Enterprise, and/ or other US DoD. This is due to the emerging roles of these vehicles in intelligence, surveillance and reconnaissance (ISR) applications. Active flow control based on dielectric barrier discharge (DBD) plasma actuators is one of the promising technologies in advancing the aerodynamic performance and maneuvering of UAVs/ MAVs, because plasma actuators are fully electronic with no moving parts such as flaps or ailerons; they have an extremely fast response, very low mass, and low input power. Particularly, they are flexible, so that they can be formed to various shapes and located on the air vehicles with relative ease. This effort directly support the ~Platform Design and Survivability~ S&T focus area. It is not only valuable basic research work, but also consistent with our China/HK S&T engagement strategy. c. Coordination: Dr. Yu~Tai Lee (NSWCCD, Code 871) is the primary researcher in NSWCCD working on flow control using plasma actuation. The research work has been supported internally by Dr. Jack Price (NSWCCD Director of Research), Dr. Michelle Skoorka (ONR N~STAR Director, Managing ILIR and IAR funding for the Naval Warfare Centers), and Code 351 (John Kinzer and Judah Milgram). d. Desired Outcome: (1) fundamental knowledge associated with DBD plasma actuators flow control, (2) experimental results from the lab for numerical method development and validation, (3) detail report of the test and analysis results, (4) conference and journal papers, and (5) potential additional future collaboration with the US partners to advance DBD plasma actuator flow control methodology.
