| 摘 要： | 印尼亚齐(ACEH)电厂取水口温升是判断工程平面布置方案优劣的关键。应用局部加密的非结构化网格建立了平面二维潮流温排水数学模型。该模型能很好地描述复杂地形,既保证了工程区域水动力计算精度,也减少了计算量。在水动力计算过程中考虑了洋流和季风等长周期动力因素,研究了温排水在这种长周期动力条件下的扩散规律。计算了不同布置方案条件下温排水的影响范围,对不同布置方案进行了评价。

| Abstract: | The cooling water engineering is a decisive factor of the power plant layout in ACEH Indonesia.In this paper,a two-dimensional cooling water model with local refinement unstructured grid has been set up.The terrain representation of the model is well so that the model could ensure the accuracy of the hydrodynamics and reduce the calculation amount.In the process of hydrodynamic calculation, ocean current and monsoon have been added to the model, and the diffusion law of cooling water under the condition has been studied.The influence scope of drainage is calculated, and the different layout programs are evaluated. |
