| 4. | Firstly we investigated the flow field and temperature field of diffusion fuel . when the direction of centrifugal force as same as the velocity of flow , there is a circumfluence of anti - clockwise 首先研究了扩散燃烧时的流场和温度场。当离心力的方向与流速方向相同时,流场有一个逆时针方向的回流区。 |
| 5. | Nowadays , swirling burners have been used widely , because they can establish central recirculation bubbles which make high temperature gas flow back so as to speed up the progress of combustion of pulverized coal 旋流燃烧器因为能够形成中心回流区,卷吸高温烟气,促进煤粉的着火等特点,在工程上已经得到了广泛的应用。 |
| 6. | When the velocity of methane is unchangeable , the more fuel / air is , the intensity of circumfluence is stronger . when the centrifugal force is added , the intensity of circumfluence is increased along with the increase of centrifugal force 当甲烷速度不变,随着过量空气系数的增加,回流区的强度增加;当加离心力时,随着离心加速度的增加,回流区的强度增加。 |
| 7. | We investigated the transformation of the flow field with the increase of centrifugal force . when the acceleration became bigger , the flow field has a main circumfluence of anti - clockwise and a circumfluence of clockwise on the downriver 研究了流场随着加速度增加的变化情况,随着加速度的增大,当离心力与流速方向相同时,流场有一逆时针方向的主回流区,在流场下游有一顺时针方向的回流区。 |
| 8. | According to the jet theory and the characteristics of the flow , the flow can be divided into 6 zones : supersonic core zone , supersonic mixing zone , subsonic mixing zone , secondary flow zone and expanding zone . the rules to distinguish these zones were established . 2 根据射流理论及引射流动特点,将引射流场结构划分为超声速核心区、超声速混合区、亚声速混合区、支板背壁回流区、二次流流动区以及发动机后部膨胀区,并确定了各区域准确划分的原则。 |
| 9. | Through the experiments we can safely get the conclusion that the cyclone burner cannot only insure the complete combustion of cws , but also can reach the need of environmental protection . in comparison with the cold experiment ( including in the infinite field and finite filed ) , numerical simulations were done using k - e standard model 结合实验结果,本文提供了在不同燃烧环境下,选择水煤浆旋流燃烧器的各种依据,其既能保证足够的回流区和回流量,使水煤浆能够稳定的着火燃烧,又能保证有效的避免结渣。 |
| 10. | The solution algorithm involves tracing the characteristic lines backwards in time from a upwind element of an interior point . two advanced mehtods , quasi - consistence and consistence hexahedral element method , for three - dimensional advective problem are developed . and comparison of these two methods with linear interpolating function method is implemented 当re 400时,流动明显地具有二维性; re 800时,流动具有一定程度的三维性,而且出现了次回流区; re 1000时,流动则具有明显的三维性。 |
