“…For example, how to deeply understand the momentum characteristics of the pneumatic actuation of the plasma to realize greater momentum injection of the airflow and accordingly generate the effective actuation becomes the research hotspot widely. [6][7][8][9][10][11] The induced airflow velocity and the body force are not only the two important factors of the momentum characteristics but also the key points for improving the flow control capability. [12][13][14][15][16] However, the airflow velocity induced by the pneumatic actuation of the dielectric barrier discharge plasma is maximally set as 8 m/s, and the body force is only several millinewton to less than hundred millinewton, which restrains the action range and the actuation effect of the pneumatic actuation of the plasma, and the physical mechanism that restrains the improvement of the induced airflow velocity and the body force is still not clearly defined.…”

Test and diagnosis of the characteristics of the air flow induced by the pneumatic actuation of the plasma are the important basis for the plasma flow control. In order to well understand the electrical characteristics of the pneumatic actuation of the plasma and the influence of the actuation voltage amplitude and the phase on the induced flow characteristics, the dielectric barrier discharge actuators symmetrically distributed were selected for the experimental research. The experiment result shows that the discharge form of the actuators symmetrically distributed is filamentary discharge, uniformly occurring around the high-voltage electrodes, and this is different from the discharge picture of the actuators asymmetrically distributed; when the voltage applied on the high-voltage electrode near to the actuators has the same amplitude and phase, the induced directional jet flow is vertical to the actuator surface, and the speed is at the order of meter per second; the change of the amplitude or phase of the voltage applied on the high-voltage electrode of the actuator can induce a jet flow towards the upper left or the upper right, but cannot effectively increase the induced airflow velocity.

In this study, the application of high velocity metal forming process by means of electromagnetic field is proposed. Electromagnetic Sheet Metal Forming (ESMF) is a process of forming sheet metal with very high speed (in milliseconds) without mechanical contact using the energy density of a pulsed magnetic field. In this process, deformation of the workpiece is driven by a transient electric current that is induced in a coil using a capacitor bank and discharge switch. This study presents some experiments and their results by examining the effects of different parameters in the proposed ESMF setup. The analysis and modelling of Electromagnetic sheet metal forming (ESMF) process is presented, as well. It has been seen that, it is possible to design a new system using the outcomes of this study.

“…The inclusion of D a and the decrease of the current di/dt can reduce the attractive force generated immediately after the initial repulsion that occurs during the forming process, namely when the deformed metal piece is very thin and presents a high resistance [10]. This is the main advantage of this circuit compared to a typical circuit using a spark gap switch device.…”

A 10 kJ electromagnetic forming (EMF) modulator with energy recovery based on two resonant power modules, each containing a 4.5 kV/30-kA silicon controlled rectifier, a 1.11-mF capacitor bank and an energy recovery circuit, working in parallel to allow a maximum actuator discharge current amplitude and rate of 50 kA and 2 kA/µs was successfully developed and tested. It can be plugged in standard single phase 230 V/16 A mains socket and the circuit is able to recover up to 32% of its initial energy, reducing the charging time of conventional EMF systems by up to 68%.
