三峡水库岸边排污的特性及数值模拟研究

NUMERICAL SIMULATION OF THE CHARACTERISTICS OF EFFLUENTS IN THREE GORGES RESERVOIR

  • 摘要: 数值模拟是研究和解决三峡水库污水岸边排污的重要手段之一. 针对三峡水库岸边污水排放的特点,分析并阐述了排污口附近的水流和污染物分布特性及其所带来的数值困难. 基于这些分析,讨论了深度平均二维模型和不同分层三维模型在模拟三峡库区岸边排污问题中的优势和不足,为库区岸边侧向排污数值模型的进一步发展奠定了基础.

     

    Abstract: Numerical simulation is an important method to study the pollution problem due to the wastewater discharge. Thefeatures of water flow and wastewater distribution andrelated difficulties in numerical simulation are discussed in the presentpaper. Both advantages and disadvantages of thedepth-averaged model and varied multi-layer models are analyzed when theyare applied to investigate the wastewater discharging into Three GorgesReservoir (TGR). The present study may be helpful to the furtherdevelopment of wastewater effluent model for TGR as well.
