【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。更多还原

【Abstract】 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.更多还原
