| 摘 要： | 通过模式选择和计算,得出烟气抬升高度的增加与动能和热能的关系,表明当烟囱出口处风速分别为3 m/s、2 m/s和1 m/s时欲增加同样大小的烟气抬升高度,需要的动能比热能要高,结论认为烟气的热力提升比动力提升的贡献大。

| Abstract: | Through choosing model and the calculating results to compare the relatives between the increases of smoke raise height and kinetic energy & heat energy.It is known that when wind speed is 3 m/s,2 m/s and 1 m/s at the end of the chimney,the kinetic energy needed is higher than heat energy.It is also known that the contribution of hot rise is bigger than dynamic rise. |
