Special Issue Information

Dear Colleagues,

Over the last few decades, the development of active control techniques, such as mechanical flaps, wall synthetic jets, micro-electromechanical devices (MEMS), and plasma-based devices, has opened up very promising and interesting potentialities for practical and industrial applications.

Among these, plasma actuators, as all-electric devices, are very interesting due to their behavior, which is characterized by a fast reaction with very high frequency response, and the without need for pneumatic, hydraulic or moving components.

The study and research of potential applications of plasma actuators for cold flow and even combustion control is growing fast due to several industrial applications, such as in the power generation industry, as well as in propulsion and land-based engine systems. Nevertheless, there are some substantial challenges for the practical implementation of such devices, such as energy requirements and efficiency, integration in existing components, and safety for high voltage feeding and for electromagnetic emissions.

Moreover, innovative manufacturing technologies, as well as additive technologies, will open a huge application field, considering their capability to operate in the microscale and multimaterial manufacturing.

Nevertheless, we are still far from fully comprehending all the several open issues in the aforementioned topics.

Given the interest in and importance of the topic, it is timely to assess the latest theoretical and experimental advances in the field of active flow and combustion control using plasma devices.

Potential topics include but are not limited to:

  • Design, characterization, and development of innovative plasma actuators for active flow control;
  • Experimental characterization and reliable numerical simulation of cold/reactive flow field and boundary layers in the presence of plasma actuators;
  • Innovative practical applications of plasma actuators for active flow control;
  • Plasma assisted cold flow control applications: Lift and drag control, laminar–turbulent transition control, turbulent flow control;
  • Plasma-assisted control of combustion and combustion instabilities;
  • Plasma actuator for noise control;
  • Plasma flow control in propulsive systems;
  • Sensor–actuator integrated systems, with a possible focus on micro-electromechanical MEMS devices;
  • Innovative manufacturing technologies for the integration of the control device in the main components;
  • Energy consumption and efficiency of plasma devices for flow control;
  • Safety issues related to the industrial application of plasma devices for flow control.

Actuators play an important role in modern active flow control technology. Dielectric barrier discharge plasma can be used to induce localized velocity perturbations in air, so as to accomplish modifications to the global flow field. This paper presents a selective review of applications from the published literature with emphasis on interactions between plasma-induced perturbations and original unsteady fields of bluff-body flows. First, dielectric barrier discharge (DBD)-plasma actuator characteristics, and the local disturbance fields these actuators induce into the exterior flow, are described. Then, instabilities found in separated flows around bluff bodies that controlled actuation should target at are briefly presented. Key parameters for effective control are introduced using the nominally two-dimensional flow around a circular cylinder as a paradigm. The effects of the actuator configuration and location, amplitude and frequency of excitation, input waveform, as well as the phase difference between individual actuators are illustrated through examples classified based on symmetry properties. In general, symmetric excitation at frequencies higher than approximately five times the uncontrolled frequency of vortex shedding acts destructively on regular vortex shedding and can be safely employed for reducing the mean drag and lift fluctuations. Antisymmetric and symmetric excitation at low frequencies of the order of the natural frequency can amplify the wake instability and increase the mean and fluctuating aerodynamic forces, respectively, due to vortex locking-on to the excitation frequency or its subharmonics. Results from several studies show that the geometry and arrangement of the electrodes is of utmost significance. Power consumption is typically very low, but the electromechanical efficiency can be optimized by input waveform modulation. Full article
