摘要：

The phase separation kinetics of a symmetric binary immiscible fluid was analyzed in the presence of ternary amphiphilic fluids. Investigations show the three-dimensional amphiphilic lattice-Boltzmann model with short-range interactions for the amphiphilic fluids. A structural order-disorder transition was observed between the sponge and the gyroid phases using amphiphile-binary fluid coupling parameters. The results show that most of the wave numbers show slow decay and long-term growth for the growth-arrested mesophases.
