In order to improve the mass flow rate of a single discharge tube to get higher output power, a new discharge tube was designed after optimization of nozzle and loop structure of the original tube. The flow field, the output power and the mass flow rate of the discharge tube were analyzed through numerical simulation and measured in experiments. The computational results were consistent with the experimental results well. The flow field and the output power of different structure of discharge tubes were compared. The results show that the mass flow rate of the newly designed discharge tube is larger, the output power of single discharge tube is higher and the glow discharge is uniform.
