PROBLEMS OF PHYSICAL MODELING OF
ELECTRIC-ARC DISCHARGES

O. I. Yas'ko

UDC 537.523

Special features of physical  modeling of high-current 
arc  discharges  are considered. It is shown that  the 
employment  of  dimensionless   criterial  expressions 
makes  it  possible  to   establish  only  approximate 
similarity   of  characteristics  for  some   specific 
apparatuses   which  govern  arc-discharge conditions. 
Procedures  to  select  the  dominant  energy-exchange 
processes  and  to  find  the  scale  values of plasma 
properties  are  presented,  whose  knowledge  permits 
modeling of the discharges initiated in various media.
