Abstract: 该文采用三次样条函数对水位梯度进行修正,建立了珠江伶仃洋河口的大涡模拟湍流模式,通过对1978年7月20日23点至1978年7月22日23点的珠江伶仃洋河口动力过程的模拟表明,建立的模式能准确地模拟潮汐的动力过程,同时,由于三次样条插值能够自然地反映河岸零水位梯度条件,本文的方法能够更清晰地反映出河岸的局部涡结构。
A large eddy simulation turbulence model for Pearl River estuary is established in this paper.Gradients of water level in horizontal plan are corrected using cubic spline.Dynamic process in Lingding Yang of Pearl River estuary from 11:00 pm in July 20,1978 to11:00 pm in July 22,1978 is simulated.The numerical results show that the proposed model can be used to predict the process correctly.At the same time,because the cubic spline can naturally be used to describe the zero gradient of water level in horizontal plan near the bank,the model can be used to describe the local vortexes near the bank clearly.
