Research on the Diffusion in Curved Micro-channel Flow Driven by Pressure
Abstract: The fluid diffusion at turn in the micro-channel driven by pressure was simulated numerically. The results show that the number of Re and the dimensionless curvature k play a significant role in the diffusion of sample. In order to lower the band broadening of sample while completing the test and separation quickly, the number of Re and the dimensionless curvature k should be lowered properly. The conclusions are helpful to the optimal design for micro-channel.
Key words: micro-channel; turn; diffusion; driven by pressure; numerical simulation.
