Fundamental Physics and Practical Applications of Electromagnetic Local Flow Control in High Speed Flows

Abstract

Abstract : Achievement of the future US Air Force mission requires development of new high speed air vehicles. The aerodynamic performance of high speed air vehicles is sensitive to local flow phenomena which may adversely affect vehicle operation and possibly result in vehicle loss. An example is the Edney W shock-shock interaction which causes intense local surface heat transfer. New concepts in local flow control for high speed flows are needed to alleviate or eliminate adverse local flow phenomena. * Recently, a promising new research field in local flow control for high speed flows has emerged - Electromagnetic Local Flow Control (ELFC). Examples include beamed energy addition (e.g, laser and/or microwave energy deposition) and DC discharge, with or without external magnetic fields. Recent conferences and workshops have emphasized the importance of ELFC and identified many promising opportunities. This report describes the research accomplishments of Rutgers - The State University of New Jersey, the University of Illinois Urbana-Champaign and the University of Minnesota in understanding the fundamental physics and practical applications of Electromagnetic Local Flow Control in high speed flows.
