Abstract:

The project objective consists in interdisciplinary investigations aimed at the development of an advanced innovative concept of flow control based on a specially designed microwave discharge generator initiating intrinsic to flow streamwise vortices with a given scale. PART 1 of the Project is the aerodynamic modeling of a boundary layer with an embedded vortical structure of a given scale generated by a system of MW discharges. Efficiency of the flow-control concept and its potential applicability is evaluated from the matched numerical and experimental results aimed to show correlation between the turbulence structure and the aerodynamic performance of the test model. PART 2 of the Project is the research related to generation of localized MW discharges as a versatile tool for the remote flow control. It shows the feasibility of the developed technique that enables to organize microwave MW discharges in aerodynamically justified patterns to stimulate and support vortical fluid motion of a given structure.
