基于三维水动力数学模型,以香溪河河口处支流库湾与长江干流为研究对象,分析了该区域在常年盛行风况下,稳定的风生流流场三维结构特征。结果表明,在风速3m/s的NNE风持续作用下,流场达到稳定状态后,总体上水平方向的流速得到了不同程度的提升;香溪河支流库湾内表层、中层水体流向与风向一致,底层流向与风向大致相反,呈补偿态势;而长江干流流向受风力影响相对较小,变化趋势微弱。
Based on the three-dimensional hydrodynamic model, taking the tributary bank Bay and the Yangtze River as the research objects, the three-dimensional structural characteristics of steady wind flow field under the perennial prevailing wind conditions are analyzed. The results show that under the condition of continuous NNE wind velocity of 3m / s, the flow velocity in the horizontal direction has been improved to some extent after the flow field reaches a steady state. The flow direction and wind direction of the inner and middle waters of the tributary bank of Xiangxi River are the same, The bottom flow direction is opposite to that of the wind direction, showing a compensatory trend; however, the flow direction of the Yangtze River is relatively less affected by the wind force and its trend of change is weak.
