【摘要】:使用二維有限體積方法,對在管流中固定位置處注入靜止固體粒子的可壓縮含灰氣體流動進(jìn)行數(shù)值模擬,討論流場和粒子在過程中的耦合,研究質(zhì)量增加和熱量變化所產(chǎn)生的非定常波系,分析物理參數(shù)在過程中的變化.結(jié)果表明,在添質(zhì)和加熱過程中,流場會產(chǎn)生不同類型和不同強(qiáng)度的非定常波,在分析其物理規(guī)律的同時,討論添質(zhì)和加熱相互作用導(dǎo)致的波系間轉(zhuǎn)換,最后求解流場中各區(qū)域的熱力學(xué)參數(shù),得到不同的流場速度和粒子溫度情況下各非定常波波強(qiáng)的相圖,定量解釋改變參數(shù)引起的非定常波變化規(guī)律.
[Abstract]:In this paper, a two-dimensional finite volume method is used to simulate the compressible flow of ash containing gas injected into a stationary solid particle at a fixed position in the pipe flow. The coupling between the flow field and the particle in the process is discussed. The unsteady wave system produced by mass increase and heat change is studied, and the variation of physical parameters in the process is analyzed. The results show that the flow field will produce unsteady waves of different types and different intensities in the process of mass addition and heating. At the same time, the transformation between wave systems caused by the interaction of addition and heating is discussed. Finally, the thermodynamic parameters of each region in the flow field are solved, and the phase diagrams of the unsteady wave intensities at different flow field velocities and particle temperatures are obtained. The change of unsteady wave caused by changing parameters is quantitatively explained.
