SCALING LAW IN TWO-DIMENSIONAL TURBULENT CHANNEL FLOW
二维槽道湍流的标度律分析

The scaling laws of velocity structure functions in two-dimensional fully developed incompressible turbulent channel flow with variable Reynolds numbers are studied. According to this paper, Scaling laws and Extended self-similarity exist in the turbulent channel flow. According to this paper, scaling exponent varies as Reynolds number changed, but the anomaly of scaling exponent does not decrease as the rising of Reynolds number. So, scaling exponent of fully de-veloped two-dimensional turbulent channel flow must be anomalous. The scaling exponent of this paper agrees well with the predicted value by SL theory, which means both results are believable.
