Residual behavior often appears near the flammability limit for lean premixed flames. Insight into it is beneficial to improve combustion performance further. Identifying normal vector of residual flame front plays a key role in revealing its structure and evaluating weights some main effects quantitatively. For present with high curvature, as polynomial curve fitting method causes noticeable error due Runge phenomenon, non-equidistant central difference proposed. Subsequently, vectors bluff-body stabilized conventional inverted 40%H2–60%CH4–air are obtained accurately their differences compared It found that there significant flow features between behaviors. The always points at upstream direction. However, middle section almost parallel horizontal direction, downstream direction next tip. In addition, around revealed. This first time has been visualized feature work provides universal accurate identify new insight dynamics.
