부유 입자가 있는 등방성 난류에 대한 직접수치모사

다국어 초록 (Multilingual Abstract)

Particle-laden turbulence is frequently observed in nature such as the atmosphere and ocean, as well as in many engineering flows. Recently, as the dispersion of pollutant in environmental problem is of more interest, the study on the particle-laden turbulence is more important both for predicting the behavior of particles and for understanding the fundamental characteristics. Isotropic turbulence is a good example of turbulence for understanding its the properties because if Reynolds number is high, small scale turbulence has universal characteristics of isotropic turbulence without relevance to large scale turbulence. Thus, using direct numerical simulation of particle-laden isotropic turbulence, we investigate the correlation of fluid velocities along particle trajectories for finding fluid-particle interaction mechanism. Furthermore, the results of present study can be applied to development of a solid particle dispersion model.
