摘要
The diffusion-based micro flow of a T-sensor with three inlets in whichvarious species are injected was simulated numerically. The results show that the Reynolds number isan important factor of affecting the efficiency of diffusion. The smaller the channel width is, themore strongly the species diffuse. The velocity gradient across the channel width plays a key rolein the diffusion of species. The conclusions are helpful to the design of micro-fluidic devices andthe analysis of data collected from such devices.
