摘要：
A statistically planar one-dimensional developing premixed turbulent flame is studied both theoretically and numerically in order to highlight a link between transition from gradient to countergradient scalar transport and the flame development. The flux is gradient during an early stage of flame development, followed by transition to countergradient transport at certain instant, which is decreased when the laminar flame speed is increased or the rms turbulent velocity is decreased.
