Abstract

Through numerical modelling techniques, data were obtained on how underwater slopes influence the dynamics of a thermal bar and the related circulations during the water body’s autumn cooling. Different geometries of the bottom topography were analyzed, aligning with configurations such as ‘‘gentle slope,’’ ‘‘stepped profile,’’ ‘‘trench,’’ and ‘‘steep slope.’’ It was determined that in the autumn, the flow structure, the formation timeframes, and the thermal bar propagation speed are significantly influenced by the morphological features of the lake bottom.

水下救援对秋季热坝动力学的影响

摘要

通过数值模拟技术，获得了水体秋季冷却期间水下斜坡如何影响热棒动力学和相关环流的数据。对底部地形的不同几何形状进行了分析，并与“缓坡”、“阶梯轮廓”、“沟渠”和“陡坡”等配置相一致。确定在秋季，湖底形态特征对水流结构、形成时间和热坝传播速度影响显着。
