| 中文摘要: |
| 考虑烟气的浮力作用，合理地选取流场的特征参数，将烟气运动和盐水运动的基本方程无量纲化，分析两者之间的相似性，得到４个定性相似准则，其中Ｒｅ数是最主要的相似准则．并举例说明缩尺的盐水模拟实验可以满足相似准则。?更多还原 |
| 英文摘要: |
| Condidering the buoyant force in the smoke movement,we have selected suitable character-istic parameters of the folwe field and normalized the sets of equations for salt-water and smoke movement. The four simulant criteria of salt-water and smoke movement wer obtained and the most impobent one of them was the Reynolds number. These simulant criteria may be satisfied with model exporiment,illuminated by example. |
