초록
An experimental study on downwardly spreading flame over slanted electrical wire, which is insulated byPolyethylene (PE), was conducted with applied AC electric fields. The result showed that the flame spreadrate decreased initially with increase in inclination angle of wire and then became nearly constant. The flameshape was modified significantly with applied AC electric field due to the effect of ionic wind. Such a variationin flame spread rate could be explained by a thermal balance mechanism, depending on flame shape andslanted direction of flame. Extinction of the spreading flame was not related to angle of inclination, and wasdescribed well by a functional dependency upon the frequency and voltage at extinction.
