Fluid flow is mathematically expressed as mapping. A dynamic system is strong mixing under certain conditions. The cohesive mixing flow is often in laminar state. By introducing chaos into a laminar mixing system, the mixing performance can be effectively improved. Residence Time Distribution, Lyapunov Exponent, Decay of Correlation, and Mixture Homogeneity are often employed to evaluate the mixing performance of cohesive mixing. New measuring techniques of flow field study, including Particle Tracking Velocimetry, Particle Image Velocimetry, Planar Laser Induced Fluorescence, etc., are quite useful in studying cohesive mixing process. Euler-Lagrange approach and Euler-Euler one are two approaches for modeling and simulation of the cohesive mixing.
