摘要
本文为潮流水域中电厂冷却水运动模型试验、数值计算与原体实测资料的对比分析。某电厂装机容量１４００ＭＷ，利用辽东湾作为电厂冷却水的受纳水体。为了研究冷却水在此潮汐水域中的运动特性，预报电厂取水水温，并为了验证数模、物模结果的可靠程度，先后进行了数值模拟计算、物理模型试验和大规模的原体现场观测。数值模拟采用具有Ｌ稳定的分布杂交法，在边界条件中充分考虑了局部地形特点，做了特殊处理；物理模型取用比尺Ｌγ，＝３００，Ｚγ＝６００，直接采用原体实测资料作为边界控制条件。进行了物模－数模、数模－原体三者资料间的对比，获得了满意的相互验证。文中简述了所用数模、物模的某些特点，着重提出了验证分析成果。通过此典型的工程研究实例，可以认为，若能妥善处理边界条件，正确选择相似准则，虽在复杂地形的不稳定水域，数模、物模仍能相当确切地重演冷却水运动的原体情况和预报工程的水力、热力效果。
The peper presents a case study which gives comparison of results obtained from physical modelling, numericalsimulation and field observations.Liaodong Bay is ugh as heat receiving water boy with large amount of waste thermal energy effluented from a 1,400MW power plant. Extensive field obervations of the water region near the plant were conducted and both mathematicaland physical modelling of the hafted effluent circulation in the hey were Performed. In numerical simulstion, the method Offractional step with L -stability was apPlied with due consideration of the local topographic characteristics in bollndarytreatment. A model test with scales of L. = 300 and Z. = 60 was thed Operated in conformity with the boundary conditionsgiven by field tests. The very good agreement shown by the comparisons indicates the adaptability of distorted model with evenrather high geometric distortion ratio provided the model is carefully designed and well calibrated.
