摘要
使用二维有限体积方法,对在管流中固定位置处注入静止固体粒子的可压缩含灰气体流动进行数值模拟,讨论流场和粒子在过程中的耦合,研究质量增加和热量变化所产生的非定常波系,分析物理参数在过程中的变化.结果表明,在添质和加热过程中,流场会产生不同类型和不同强度的非定常波,在分析其物理规律的同时,讨论添质和加热相互作用导致的波系间转换,最后求解流场中各区域的热力学参数,得到不同的流场速度和粒子温度情况下各非定常波波强的相图,定量解释改变参数引起的非定常波变化规律.
We investigate numerically unsteady wave patterns causing by injecting particles in one-dimensional pipe flows. Numerical simulations are performed using two-dimensional and axisymmetric vectorized adaptive solver. Coupling interaction of particles and flow and variation of flow parameters are highlighted. It is found that several kinds and intensities of wave patterns induced at different particle temperature and flow velocity are shown. We discuss wave patterns resulting by adding mass and heating interaction. Physics parameters in these flow field regions are given. In addition, phase diagrams about intensity of wave patterns are obtained to show flow field influenced by changing parameters.
