摘要
对于两相流中由于颗粒存在会增强或减弱连续相湍流强度的实验现象,本文提出了一种改进型k-ε模型,对轴对称气—固射流进行的计算能在模拟该现象方面有明显的改进。
An improved κ-ε model is presented to simulate the experimental phenomenon that the turbulence intensity of continuous phase flow varies due to the existence of particles in two-phase flow. Significant improvement is achieved in the calculation of axi-symmetric air-solid jet.
