A numerical technique is proposed for determining the distributions of electric field and charge density in the case of a positive corona discharge in gas in the point–plane geometry. This technique is based on the boundary and finite elements methods for obtaining the harmonic and space charge components of the electric field, respectively, and on the method of characteristics to determine the...

This paper introduces Artificial Neural Network (ANN) method for measuring voltage in the Optical Voltage Transducer (OVT) using one or more electric field sensors. In order to obtain an accurate voltage measurement with minimum number of sensors, first the locations of sensors are specified by quadrature method. Then the electric field intensity at these locations is provided to ANN for the ca...

To calculate and evaluate wave scattering and penetration of electromagnetic waves in different biological tissues it is necessary to use a realistic model of the human body, with all tissues resolved and separately assigned with appropriate electric/magnetic properties. We report the development of a realistic 3D whole-body human model that has been adapted for simulation in CST software, cont...

The electric field fire extinguishing technology is an efficient, clean, and new that can be operated at a long distance. In order to study the synergistic mechanism of “electric-flow-heat” in process transverse AC extinguishing, ionic wind formed by influence on each charged particle during burning ethanol–air diffusion flame simulated non-premixed combustion model, experimental phenomenon que...

This paper presents numerical simulations of incompressible fluid flow problems in the presence of a magnetic field. The equations governing the flow consist of the Navier-Stokes equations of fluid motion coupled with Maxwell ́s equations of electromagnetics. The study of fluid flows under the influence of a magnetic field and with no free electric charges or electric fields is known as magnetoh...
