Turbulence Control Through Selective Surface Heating Using Microwave Radiation.

摘要

The project aims at a search and development of innovative engineering solutions in the framework of the formulated flow-control concept based on thermal initiation of given-scale streamwise vortices. The objective of the implemented interdisciplinary research is the development of operation flexible and energy advantageous control of turbulent flows using microwave (MW) methods to generate a spanwise-regular temperature boundary condition. Two mutually complementing parts of the project were implemented in the fields of aerodynamics and electrodynamics. PART 1 (Hydromechanics Institute, National Academy of Sciences of Ukraine, IHM NASU, in collaboration with National Aviation University of Ukraine, NAU) - Fundamental aerodynamic investigations consist of matched experimental and numerical studies of boundary-layer characteristics under the condition of remote heating of local flow areas with dosated MW irradiation. PART 2 (Moscow Radiotechnical Institute, MRTI, RAS, Russian Federation) - Electrodynamic investigations are focused on a search of flexible, inertialess and reliable engineering tools for active and remote flow control based on the specified spanwise-regular heating of a near-wall flow.
