英文摘要: In order to implement the transport of sediment, one-dimensional numerical simulation method based on sedtran05 is proposed. Firstly, considering the density and viscosity of water, the settling velocity, and the transfer equation, the calculate method of vertical profile model is built. Secondly, the Yellow Sea environmental conditions simulation experiments are carried out based on sedtran05 model, calculating the sediment transport rate for different particle of sediment, depth, speed, temperature of seawater. Finally, by comparing the data with other literature with the simulation results, we verify the validity of method and define the scope of application of the model.
中文摘要: 针对海洋悬浮物运输问题,研究了一种基于sedtran05模型的数值模拟方法。首先,考虑水的密度和粘度、沉降流速,以及传输方程,搭建了基于垂直剖面输沙模型的计算方法;然后,采用sedtran05模型对黄海环境进行模拟,计算了不同粒径大小、水深、流速和温度时的悬浮物输送率,并对模型相关参数进行了修正;最后,通过将仿真结果与文献数据进行对比,验证了方法的有效性并明确了模型的适用范围。
