Based on the measurement principle of plugging method and the changes in the relationship between temperature and resistance of thermistor, this study explores the flow distribution of backflow combustor of a micro jet engine. The experimental results show that with the increase of the inlet flow of the combustion, the flow distribution of different airflow channels on the wall of the flame tube will change in the micro backflow combustor. When the combustor’s inlet flow is relatively large, the flow distribution approaches to the value calculated by the area method. At the same time, the experimental results show that this method is suitable for the study of flow distribution.
