The acetylene/air counter flow flame formed by a porous cylinder in electrical fields was studied experimentally and numerically. The temperature and OH radical distributions in the flame were measured in experiments. The numerical simulation with a detailed reaction model was conducted to explore the effect of ionic wind on the flame behavior. The experimental results show that the temperature and OH radical distribution shifts to the negative electrode side in electrical fields, which is good agreement with the prediction. It is indicated that the shift of flame zone in electrical fields may be due to the change in the bulk flow velocity induced by the ionic wind.
