【摘要】 本文应用平面二维不恒定流数学模型成功地模拟了不恒定分离流的回流。通过与相应的明渠不恒定分离流的试验结果比较,流动图案、回流长度及正反向最大流速均相吻合,从而证明本文所依据的数学模型是正确的。更多还原

【Abstract】 A simulation of unsteady separating flow in an expanding flume is presented in this paper. The numerical modeling is based on a general horizontal 2-D mathematical model of unsteady flow. It is verified that the flow pattern, whirlpool length and maximum reversal velocity reasonably agree with the data from flume tests and this result could be an additional proof of the validity of the earlier developed mathematical model.更多还原
