| Abstract: | Abstract The authors created a 30 m long physical model. Many sampling points are arranged on different location of the model. By collecting sample at the real time, chemical concentration, viscosity, and other properties of binary compound system were measured separately. Results from the experiment show that from model import to model export, the chemical concentration and viscosity of binary system is gradually declining. The loss of surfactant concentration is much larger than that of polymer concentration, and viscosity loss of the binary system is greater than concentration loss of polymer. |
