The flow separation control over rotating rotor blades in hover using an alternating current dielectric barrier discharge (AC-DBD) plasma actuator is investigated through numerical simulation, possibly for the first time. Three-dimensional unsteady Reynolds-averaged Navier–Stokes calculation with a Reynolds stress turbulence model adopted to resolve airflow. impact of AC-DBD on airflow modeled ...

This manuscript presents a successful application of the inverse feed-forward control (IFFC) technique for Tollmien–Schlichting (TS) waves over wing profile placed in an open-circuit wind tunnel. Active cancellation two-dimensional broadband TS disturbances is performed using single dielectric barrier discharge (DBD) plasma actuator. The measurements required IFFC are with microphones, instead ...

Plasma actuators generated by surface dielectric barrier discharge are developed for controlling flow in aeronautics applications. This research studies the simulation of cold plasma at atmospheric pressure coupled with compressible fluid dynamics using COMSOL Multiphysics 5.4. Modeling air high voltages is carried out two dimensions. The development electric field and space charge density disc...

The continuously increasing complexity of fabricating microelectronics devices has made it necessary to consider utilizing feedback control during plasma processing steps. To investigate and optimally select control strategies, comprehensive plasma equipment models are required. This paper describes a versatile simulation tool, the Virtual Plasma Equipment Model (VPEM), that has been developed ...
