Abstract : The electrical properties of highly ionized, high temperature flames have been investigated to determine the interaction of the flame with electric and/or magnetic fields. With electric fields alone, no deflection is obtained because the field intensity within the flame is too small whether the field electrodes are outside or inside of the flame. Most of the potential drop between the electrodes occurs at the boundary layer on the electrodes. (With the unseeded flame, however, electrostatic deflection up to 45 degrees was readily obtained.) A combination of transverse electric and longitudinal magnetic fields produced a Lorentz force on the flame of 10 newtons/cu m; this force deflected a highly ionized flame up to 45 degrees. The deflection is proportional to the Lorentz force and inversely proportional to the inertial force. The magnitude of the flame conductivity (i.e., ionization) determines the power supply requirements for the electric field; the power required for the electric field decreases with increasing flame conductivity.
