Conclusions

In this project, we successfully use the finite element analysis to simulate the evaporation and rehydration process of an aqueous polymer two phase system. In the real situation, it is a complicate dynamic process. We cannot easily calculate the droplet volume or contact angle over the elapsed time, which is important for sample concentration calculation in the biomedical application. By this simulation method, the evolution of contact angle, surface area and volume can be calculated and be compared with the experimental results. Once we find out the correlation between the simulated and experimental parameters, we can simply change simulation parameters to evaluate the effect of substrate roughness, environmental temperature and humidity in the evaporation and rehydration process. It can help us to modify these parameters and improve the experimental result.
