Abstract :
The analytical model of positive streamer in weak external field is described and used to calculate the number of chemically active species, generated by streamer in air. Comparison is made with two-dimensional numerical simulation of streamer in a 5-cm discharge gap between hyperboloidal anode and a plane cathode. It shows that the model well predicts the mean streamer parameters and number of major components (oxygen atoms and excited nitrogen molecules) produced by the streamer
