初步探索风场对水交换的影响,设计典型算例,开展了数值模拟,分析了风速、风向和周期等风场特征参数对水交换的影响。模拟结果表明:在现实可能风场范围内,风向决定风场对水交换是否有影响;风速决定影响程度的大小;周期对水交换的影响较小。为了有效利用风场实测资料,探讨风场的时空变化对水交换的影响,以及应对实际应用中可能缺少风场资料的情况,以渤海湾的实测数据为基础,利用上述结论研究了风场数据的处理方法。在不同的时间尺度上对风场数据进行了平均化处理,并以平均后的结果为代表风参数,模拟了渤海湾的水交换。结果表明月能量平均风场和季度能量平均风场的水交换模拟结果与真实风场的水交换模拟结果非常接近。
The influence of wind field on water exchange was explored. Typical examples were designed and numerical simulation was conducted. The influence of wind parameters such as wind speed, wind direction and period on water exchange was analyzed. The simulation results show that the wind direction determines whether the wind field affects the water exchange in the realistic wind field range, the wind speed determines the impact degree, and the period has little effect on the water exchange. In order to effectively use the measured data of the wind farm and explore the impact of the spatio-temporal changes of the wind farm on the water exchange, as well as the possible lack of wind farm data in practical application, the wind farm data The method of treatment. The wind field data are averaged on different time scales. The mean wind parameters are taken as the representative wind parameters to simulate the water exchange in the Bohai Bay. The results show that the simulation results of water exchange between the monthly average wind energy field and the seasonal average wind field are very close to those of real wind field.
