Numerical Analysis of Electric Wind in Corona Field

Abstract

Two-dimensional digital model for analysis of direct current corona field and induced electrohydrodynamic air flow field in wireto-plane electrode system is presented. The model based on the finite-difference method in polar coordinate system for corona field computation suitable to use in usual personal computers. Results of computation of current-voltage discharge characteristic are compared with experimental one. The digital model of electrohydrodynamic air flow field consists of finite-difference approximation of the Navier-Stokes equation and the continuity equation in Cartesian coordinates. Digital velocity values are checked experimentally. Ill. 10, bibl. 7 (in English; abstracts in English and Lithuanian).

An Electrostatic Approach to the Numerical Simulation of Combined Corona and Electrostatic Field in Three-Electrode System

“…The first region corresponds to Laplacian field, and the second one is occupied by corona field. The field in the first region is quasi-homogeneous, the grid in Cartesian coordinates can be used for solution of Laplace equation [10]. Potentials of the points given in Table 1 and calculated by using equations ( 3) and ( 6)-( 9) are given in Table 2.…”

“…Potentials of the points given in Table 1 and calculated by using equations ( 3) and ( 6)-( 9) are given in Table 2. Polar grid is used in [10] for computation of corona field in wire-to-plane electrode system similar to that located in the area to the left of separatrix in Fig. 1.…”
