The flow field is simulated by a vortex method, and the diffusion of matter is calculated through a method analogous to the vortex method. The numerical result demonstrates that the particle method can indeed simulate the entrainment of matter into the shear layer due to the rotating motion of the large-scale eddies. The calculated mean concentration and fluctuation intensity indicate the self-similarities in accordance with the existing numerical results. It is also shown that the mixing asymmetry due to the large-scale eddies is successfully simulated.}, pages = {839--846}, title = {二次元混合層における物質拡散の粒子法解析}, volume = {70}, year = {2004} }
