| 中文摘要: |
| 本文用求解流体力学基本方程组的方法(场模化)以盐水运动来模拟研究室内的烟气运动,在数值计算中考虑了重力(浮力)的作用,引进了空度的模化方法,并且自编了相应的三堆计算程序,验证了室内烟气运动的几个典型现象,所得计算结果基本合理。 |
| 英文摘要: |
| It is proposed to simulate smoke movement in a room fire bu salt-water movement.The flow process of the salt-water is studied by formulating and solving a set to governing equations.In the computation,the buoyancy effect is considered and the porosity methed is adopted.Some typical results of smoke movement in a room fire are verified by using of three-dimensional computer code.The computational results are plausible. |
