Plasma Influence on Characteristics of Aerodynamic Friction and Separation Flow Location

摘要

This report results from a contract tasking Moscow Technical Company- Institute of High Temperature RAS as follows: The contractor will study the application of plasma technology for flow control. In particular, he will study the change in aerodynamic friction and the flow separation point using various electric discharges near a model's surface. He will analyze experimental data obtained previously at his lab (and elsewhere) in order to define better- oriented experiment. The investigation will then be made on a simple model namely a plate. Three types of surface discharges will be tested in this work, (a) HF multi-streamer discharge; (b) micro-hollow cathode discharge and (c) glide surface discharge. It is thought that the most interesting for the aerodynamic application will be HF micro-streamer pulse repetitive discharge. Therefore more emphasis will be made on the latter. The main emphasis of the comparison will focus on the energetic effectiveness of the plasma influence.
