摘要
气相采用RNGk-ε模型与SIMPLEC算法,颗粒相采用单颗粒轨道模型,对二维横向紊动射流的颗粒进行数值模拟,结果表明:射流孔越大的流场,颗粒偏移的程度越大;射流比越大的流场,对靠近射流孔的颗粒影响越大。
The trajectories of particle in 2-D turbulent jet-to-crossflow were simulated, by using RNG k-ε model and SIMPLEC algorithm for gas phase and single trajectory model for solid phase. The result suggest that： With the increase of D, the offset of particle was more and more. With the increase of R, the particles near the exit of jet were affect more great.
