Numerical Analysis of Electric Wind in Corona Field
AbstractTwo-dimensional digital model for analysis of direct current corona field and induced electrohydrodynamic air flow field in wire-to-plane electrode system is presented. The model based on the finite-difference method in polar coordinate system for corona field computation is 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).
