摘　　要：从相似原理、冷却水物理模型的特点及模拟方法、变态模型三个方面论述了水力－热力物理模型，采用垂向几何变态的必要性和可能性以及存在的问题，并在前人研究的基础上，提出自己的认识和看法，具有一定的参考价值。Based on the Previous studies,the paper presents briefly a state of art of the thermo hydraulic modelling of cooling water circulation according to similarity criteria.Emphasis is put on the discussion of the negative response of the model′s geometric distortion and the possible way to approach the problem.It is concluded that a careful designed thermo hydraulic model could be a useful tool in predicting the thermo hydraulic behavior of the cooling water circulation.Further research is necessary to get a deeper quantitative analysis of the model′s scale effects.
