An experimental study was carried out to investigate 
the  flow  pattern  of  a  pulsed  periodic  gas jet 
at Re 4000 and  a  modulation  frequency  of 200 Hz. 
Application  of  conventional  and   nonconventional 
optical methods of visualization  of  the flow field 
allowed  a conclusion about the formation of several 
large-scale vortices by every pressure pulse.
