TL;DR: In this article, a boundary problem about the DBD generation near a flat dielectric plate is proposed, and the results of numerical modeling of the incompressible Poiseuille and Couette flows under the time-averaged transverse force impact of DBD actuators placed along the main flow are presented.
Abstract: Numerical research of the gas pressure influence on a conduction current in a dielectric barrier discharge (DBD), the average volumetric force acting on gas from the discharge, and the power of heat release in the discharge is carried out for aerodynamic applications. The calculations are implemented with use of the earlier proposed boundary problem about the DBD generation near a flat dielectric plate. This problem statement takes into account such factors as the finite thickness of the exposed electrode, finite rates of desorption and the recombination of charged particles on the dielectric surface, and the electric field induced by a superficial charge. Represented are the results of numerical modeling of the incompressible Poiseuille and Couette flows under the time-averaged transverse force impact of DBD actuators placed along the main flow. The possibility of significant influence of an additional transfer of the main flow momentum due to the cross-flow (induced by actuators) on the structure and the characteristics of the considered shear flows is demonstrated.

TL;DR: In this article, an unsteady flow around a NACA 0012 airfoil at a fixed Reynolds number of 40,000 is performed using several multi-block overlapping grids of different scales and densities, which cover settlement areas of various extents, including the near and far wakes.
Abstract: Parametrical calculations of an unsteady flow around a NACA 0012 airfoil at a fixed Reynolds number of 40,000 are performed using several multi-block overlapping grids of different scales and densities, which cover settlement areas of various extents, including the near and far wakes. The solutions found by Menter’s shear stress transport model, the Spalart–Allmaras vortex viscosity transport model, and the method of vortical domains, are compared with available estimated and experimental data. Verification of the two-dimensional model is performed by comparison of the numerical predictions for a cross flow over a thick plate with Igarashi’s experimental data.
