A  study  of  the  induced  flow  pattern,  in quiescent  air,  by  the  trielectrode  plasma  curtain  (TPC) discharge  is  presented  and  analyzed  in  terms  of  the electrical  characteristics  of  the  discharge.  The  TPC discharge  is  based  on  the  combination  of  a  dielectric barrier  (DBD) with  a  corona  (CD)  discharges  in  a  three electrode  system,  and  basically  it  consists  in  the “stretching”  of  a  pure  DBD  by  the  action  of  a  negative corona discharge generated between the active electrode of he dielectric barrier and a remote  third electrode.  It wasfound  that  the observed  flow pattern  is mainly controlled by  the  forces  exerted  at  the  vicinities  of  both  exposed electrodes  where  the  electric  field  is  very  high.  On  the other  hand,  the  net  force  produced  at  the  inter-electrode gap  seems  to  be  very  small  in  spite  of  the  large  current lowing there, a fact that can be attributed to the relatively low value of the electric field at the streamer channel.
