摘要
Diffusion of particles in two-dimensional sieves with microscopic obstacles were simulated by RWS-C program~([1,2])based on the random walk theory.A two dimensional sieves with irregular quadrilateral(Fig.1)was constructed.and the particle diffusion processes in this system were simulated.The particles diffusion were evaluated quantitatively by the separation angles analysis for large number individual particle trajectories.We focus on the diffusion separation of molecules,and some influence factors such as the driving velocity,random thermal velocity of molecules and the size of the sieves were calculated based on our simulation results.The results show that,the separation angles becoming more diversified with the driving velocity decreases(Fig.2),the structure of the irregular quadrilateral and their gap sizes were important factors for the particles separation.These simulation results provide a theoretical basis for the design of micro-nano separation devices.
