The stabilization characteristics of turbulent premixed jet flame with having applied electric fields have been investigated experimentally. A single electrode configuration was adopted such that electric fields were applied directly to nozzle and thus the surrounding could be an infinite ground. The experimental results showed that the velocities for partially-detachment and blowoff increased with having applied AC electric fields. The functional dependency of voltage on maximum blowoff velocity were quite different in terms of equivalence ratio. The effect of applying electric fields to turbulent premixed flames were discussed in detail.
