Effects of hydrodynamics on a model surfactant system

Using a one parameter free energy model for surfactants, we numerically stu dy the effects of hydrodynamics in the microemulsion and lamellar phases. O ur results show that the dynamical correlation function has temporal oscill ations for a range of hydrodynamical coupling strengths in the microemulsio n phase. Our results are in qualitative agreement with methods based on per turbation expansions about the coupling constant. (C) 1998 Elsevier Science B.V. All rights reserved.
